Btw the topic name is a response to her saying "Because if it were true I wouldn't be able to blame Kairi-san anymore."
And also her brother never tried finding her. Like he just kept a memorial childhood toy like she did, but except that as he looks so free and homeless etc he could have tried another way to live... for example finding his lil sis and start a new life with her or something, but he looked more like he was just out of all and didn’t care about anything anymore. It’s sad cause mentally one way or another everyone get these moments of pointless living and losing themselves to the point your fucked in head and do abnormal shit.
Not saying you shouldn't blame Kairi...Well maybe you shouldn't blame him. After all her brother was doing some really illegal and immoral shit (I probably would beat the shit out of him too but not kill him. I would run and report him). Maybe not blame him but hold him EXTREMELY accountable. But anyways, ppl change. People change all the time. Sometimes it's in the things they like and the activities they enjoy. Sometimes it's their mentality. And of course people change physically.
You can't expect someone to be the exact same person as when they were like 7. It's unrealistic and unhealthy. She needs to get over her image of her brother when he was younger. Not saying she should've expected him to be evil but she can't keep thinking he was gonna be the same type of person. It can't possibly be easy for her to do that but she needs to nonetheless.
