I agree. Her unnecessary kindness is bothering me. She should have seen this assassins as monsters as well since they kill for money.
But if she starts klling people, she will definetly be seen as a threat by everyone around her and the royal family. They have been leaving her alone because they believe she won't do anything bad but once she commits a crime, there really is no way to defend her anymore. There are already bad rumours about her and there are other countries and nobles that want any excuse to get their hands on her so it's not realistic for her to just kill them.
The reason why they can do those things because she haven't killed anyone. Once she do it, she will be labeled as disaster....much more maybe a Demon King herself....well of it's me, I'll kill of course. They never seen me as human anyway, I'll just gonna probe them right (▰˘◡˘▰)
Girl, even Patrick says it's okay to kill so just kill those who tried to assassinate you, this obviously won't stop them from killing more people in the future and they probably have killed so much more in the past, also she definitely won't do this but she really should kill the maid, idc if the maid has a reason but if I were in MC's position, even if I'm strong, when a person who tried to kill me once especially if they were someone I knew, I'd kill them because that means they betrayed me even after knowing who I am, if they're stupid enough to try to do that, what's gonna stop them from doing the same thing again
