The people calling her a fool or dumb seem to really lack critical thinking , she may have lived for multiple lives but she never became an adult in them , she always died as a CHILD , maturity here doesn't work like this , she has always been a child , A TORTURED ONE at that so she never experienced being a full fledged adult , she was just a little kid reapedetly dying without ever knowing what it means to mature or grow up , so she will of course still have a child mindset + she couldn't experience childhood , and that adds up to why she acts childishly sometimes , even ADULTS who meet problems at their childhood act like kids at times , so why are you guys mad at a KID acting like ONE
