She didn't brainwash him, that's all him. It's he's been since his last life, before she met him. She just found out how he is and is running screaming. He's a psychopath. She found out he tried to kill Dietrich and has been lying to her about it, eventually even winning heart and body.
Billoi is not at fault, but neither is Rein. She chose to birth him, not blaming him for Wilhelm's actions. She took care of him as long as she could till her trauma didn't let her be around him and then she gave him to Dietrich to care for. "Trash mother" is wild, he's a rape child and she tried her best. She was ordered to give him up to the imperial family

I respect your opinion ٩(๑❛ᴗ❛๑)۶
still Either way she is still a trash mother, same with the ML. Him and the FL can be gone for good. She only wants to learn the truth one sided and yeah she maybe take care the son but what?? Give him the same trauma for neglecting him. Just because you have trauma you gonna do that to that poor child. Like no way!
Even dietrich treated the kid like her own son. She and the ML has the problem and taking it out on the poor child is not an excuse. She is still trash for not treating the son right. She should let the child be adopted...
The 2nd child was made by force as well if we will summarize what happened but she treated the 2nd child better than the first one soooo I still hate her same with the ML. ┑( ̄Д  ̄)┍
In chapter 80, where he called the ML "Devil", she is a "Devil' herself.

You're contradicting yourself. Just like you said, she knows he is a psychopath but she still chosed to leave her son to the guy who made her suffer. Yes she chosed to give birth to Billoi, but for what? She saw how scared he was, but she ignored him, she could not stand to look at him, she didn't even try to reassure her little boy when she handed him over to that madman. She then declared that she would not see Whilhem ever again, which means that she did not intend to visit her own child. A trash mother is what she is. What's the use of giving birth to a child you won't give love to? Also, for Billoi it was not rape. She slept with Wilhelm because she wanted to.
She used Whilhem and he used her. They used one another. She thought she could have him in the palm of her hand, as her pawn, as long as she showered him with love. He was the emperor's son, he was to become extremely strong, and she wanted to use that to her advantage.
What she didn't know is that he didn't have the mind of the innocent child she imagined him to be. He only knew hatred, violence, war and death. So he naturaly became obsessed with her and wished to have her for himself, vowing to eradicate whatever stood in his way. It's not surprising in his case knowing he never experienced love. He doesn't know how to properly love someone.
But in her case, she had the love of her parents, of Dietrich, many other and was aware of the pain one could feel when separated from their loved ones, Needless to Say a parent. And yet, she abandoned her own kid. A trash mother and father.

"You're contradicting yourself. Just like you said, she knows he is a psychopath but she still chosed to leave her son to the guy who made her suffer."
She didn't "choose" to, she was ordered to by the imperial family because he has imperial blood. She was ordered to.
"Yes she chosed to give birth to Billoi, but for what?"
She says for what, it's because she doesn't want to kill an innocent baby just because she hates the father. Probably the same reason she kept this new daughter that she got pregnant with when Wilhelm raped her for 3 days straight.
"She saw how scared he was, but she ignored him, she could not stand to look at him, she didn't even try to reassure her little boy when she handed him over to that madman."
He was a rape child that she didn't want to abort. She became unable to look at him because he started to resemble his father. She had no choice but to give him up. It's called post partum, she wasn't able to connect with him because of her trauma so she gave him to her closest friend to raise when she no longer could until the father decided to use him to bring Rein to him so he could try to convince her again, only to end up raping her for 3 days.
"She then declared that she would not see Whilhem ever again, which means that she did not intend to visit her own child."
Yes, Wilhelm just raped her for three days and Billoi is out of her hands because she is being ordered to leave him there. She does not want to be around Wilhelm and she did the best she could for the son until she couldn't anymore. She already gave birth to him despite the circumstances, fed him with her own breasts, cared for him for years till she couldnt anymore and left him in the living care of her closest friend.
"She used Whilhem and he used her. They used one another. She thought she could have him in the palm of her hand, as her pawn, as long as she showered him with love. He was the emperor's son, he was to become extremely strong, and she wanted to use that to her advantage."
The difference is that she used him as a knight in a medieval setting, where being a knight is a noble profession and she did so with a feeling of guilt while also raising him while treating him as a mother would a son while as his manipulation of her was to try to kill someone close to her because he didn't like that she was too busy crushing on him to look at her adopted son (Wilhelm) as a romantic partner. He literally made her fall in love with him and give her body to him and then she found out it was all fake...
Imagine trying to make an argument that "they used each other", it's very clear you need to reread

Rein handed him over to her most trusted friend to care for him when she couldn't, I'm really not sure how you view that as "abuse" or even malicious. She just couldn't bond with him because he looks like his father and his father did some unforgivable shit. The son doesn't realize what his father did

Yes she was ordered to hand over her son to him. But when did she ever Care about the royal family's orders? She literally stabbed that trash's leg and plotted to destroy the royal family. Oh but that's not her fault if she has to give her son to a manipulator, a rapist and a killer, right? You're once again contradicting yourself. Billoi is not a rape child, her daughter is. She slept with Wilhelm willfully and conceived Billoi through it.
If she was such a beautiful soul, even if she couldn't stand the sight of him, she should have fought for her son, so that at least he would not have to endure that sorrowfull life in the imperial palace.
Please stop lying to yourself. That woman is not stupid. Of course she knew that old man would ask her to hand over the child. That snake would never have ignored the existence of a potential heir, and knowing her, she certainly expected it. If she was so pure toward her child, she would have hidden her pregnancy, then her kid, so that he would be safe from all this madness.
Imagine justifying leaving an innocent kid in an abusive environment.
You keep blabbering about how wonderful she is for giving birth to a madman's kid despite her suffering. That's not Amazing, but pityful. "She handed him over to her most trusted Friend"? What a joke. That kid wants his mother, not a replacement.
She resented the whole royals, miraculously found Whilhem and made him her knight, because she was aware of his strenght, his link to the royal family, and the menace he represented for Michael. For God's sake just imagine if Whilhelm did not have his memories. A noble profession? Please don't make me laugh. A sixteen year old boy, sent to war for years against barbarians in that harsh weather, witnessing deaths and causing deaths. she felt guilty but did it anyway because it brought her Closer to her revenge. Otherwise, she would have let him live quietly, away from all this toxic life.
Wilhelm was already crazy, in his past life and also in the present. The only reason her plan went smoothly was because he was aware he was being used and accepted it silently, but otherwise, he also had the right to feel betrayed. He was ready to be her pawn as long as she looked only at him, and that is his madness. She on the other hand, thought that she was the one controlling everything, while she was also being manipulated and that's what choked her.
At the end, they both are crazy. He was raped, and he raped. She was an orphan, and she abandoned her child. They were used in their past lives, and they used one another in the present. Both of them manipulated the existence of the other

I don't think you know what "contradiction" means. Her acting one way against the royal family in certain conditions and acting another way towards the royal family in different ones is not a "contradiction". Also, pay attention to the story, she knew she would only face banishment for stabbing him in the leg because she was, herself, royalty. Now she has her territory back and people to care for. It's like context shifts...
"Oh but that's not her fault if she has to give her son to a manipulator, a rapist and a killer, right?"
Literally no? Like what? Do you understand what being given orders means?
"Billoi is not a rape child, her daughter is. She slept with Wilhelm willfully and conceived Billoi through it."
I'm pretty sure that even legally, sex with someone under a complete falsehood could be considered rape. But legality aside, the context here is that she consented to sex with him under the understanding that he didn't literally try and kill her best friend in order to devoid her of her first love so that he could take his place and woo her till she fell in love and gave him her body...
She fell in love with him and still struggles with the reality that he was the cause of all her suffering involving Dietrich for years while he pretended to not be the cause and did everything in his power to win her over in her ignorance.
"If she was such a beautiful soul, even if she couldn't stand the sight of him, she should have fought for her son, so that at least he would not have to endure that sorrowfull life in the imperial palace."
No, yeah. You really don't understand the concept of being given orders by a ruling body... The sorrowful life should be blamed on the father, who's custody he's in. It was his responsibility to give him a good life. Do you understand custody?
Your argument is so dumb, "she can only be a good mother if she fought the empire (in this case literally probably equating to war)"...
"Imagine justifying leaving an innocent kid in an abusive environment."
To be clear, where REIN left him was in the loving care of Dietrich, until Wilhelm used returning him to the imperial family to being Rein in, resulting in Billoi residing there by imperial decree.
"Please stop lying to yourself. That woman is not stupid. Of course she knew that old man would ask her to hand over the child. That snake would never have ignored the existence of a potential heir, and knowing her, she certainly expected it. If she was so pure toward her child, she would have hidden her pregnancy, then her kid, so that he would be safe from all this madness."
It's so funny that you say that! Because SHE DID! She literally did try to hide him, did you not remember when Dietrich said the child is his? Wilhelm only finds out the kid is his through the emperor. The emperor was looking into Rein because her abandoning him is reflecting bad on the imperial family. He found out the kid looks like Wilhelm, which made him realize and come up with the idea of using the child to bring her to him.
"You keep blabbering about how wonderful she is for giving birth to a madman's kid despite her suffering. That's not Amazing, but pityful. "She handed him over to her most trusted Friend"? What a joke. That kid wants his mother, not a replacement."
Again, he's a rape child and she had post partum. The child does not know the circumstances of his birth yet. Holding onto a kid you can't love isn't as amazing as you're making it out to be. She gave birth to him because she didn't want him to die for Wilhelm's mistakes. That's... Explicitly the story. It's not a matter of arguing whether or not that was the case. Go back and read. Your thinking is so shallow. It stops at "she mother", you're like a caveman. It takes no context into account.
"For God's sake just imagine if Whilhelm did not have his memories. A noble profession? Please don't make me laugh. A sixteen year old boy, sent to war for years against barbarians in that harsh weather, witnessing deaths and causing deaths. she felt guilty but did it anyway because it brought her Closer to her revenge. Otherwise, she would have let him live quietly, away from all this toxic life."
What? "Imagine if the story was different" is another dumb argument. THAT he had his memories paints all of this in a different color. And mentioning that knighthood is a profession in this era is relevant so I'm not sure why you're arguing... He did all these battles before, for the prince. That he's a regressor makes his "sacrifice" for Rein a lot less. Just obviously. He knows how the battles will go and arguing how the battles may have effected him when he's literally a hardened tactician/commander is kinda just dumb. "Poor him having to do battles again when he doesn't express that to be an issue, in a medieval setting where people just... Do that as a profession... While already knowing how the battles will go".
"she felt guilty but did it anyway because it brought her Closer to her revenge. Otherwise, she would have let him live quietly, away from all this toxic life."
She felt guilty because that was at a point in the story where she didn't know he was a regressor that had his memories and had ALREADY done all these battles for the prince, who he wasn't even in love with.
The thing is, she didn't need to feel guilty at all because of that reality and because he offered to do it for her because he loves her. You act like she have him an ultimatum... She didn't threaten him, he did it out of loyalty and love. Well more specifically out of his obsession with her, he would do anything for her, which is itself a form of loyalty and love. Just one that doesn't spare her.
"Wilhelm was already crazy, in his past life and also in the present. The only reason her plan went smoothly was because he was aware he was being used and accepted it silently, but otherwise, he also had the right to feel betrayed. He was ready to be her pawn as long as she looked only at him, and that is his madness. She on the other hand, thought that she was the one controlling everything, while she was also being manipulated and that's what choked her."
Again, they aren't equal at all. Rein's "manipulation" of him involved consent from him to be her sword and didn't have to do with fabricating reality or shattering his world by killing someone he loved. She also didn't make him fall in love with her or take his body while he was under a fabricated understanding. Both of which are invasive as fuck. Boo hoo, poor him having to be a knight in a medieval setting when he was already in that position in his last life. Poor him CHOOSING to do that for her.
You're just horny. He's not going to fuck you though.
Ths hypocrisy of this FL LMAO!!! OH MY BLOOD!! Just wow! I never hated a FL so much like I have felt for her. A trash mother and a spouse. She maybe have a super bad trauma because of so many deaths in her life but the fact that she do the same to her own son makes her more trash like those people who killed her family.
She is the one at fault for brainwashing the ML and when the ML is obsessed to her she has this guts to be the victim just because she discover a secret... Like dude! The child is not at fault. And we have the ML omg my blood is boiling!
Tbvh, I hope his son has this ARC where he is a grown up man, and revenge should happen... This is how Villain Made.
