Hold on, before we go on a witch hunt against Ragna, didn't Jin kill people as well in Ikaruga? Why isn't he a murderer? Now if someone can correct me please do, I don't really remember much about CT or CS for that matter. So if someone can point me in the right direction I would be much obliged. But anyway, he did kill people yes? Why isn't Tsubaki all uptight about that?
Regardless, Ragna is still one of the FEW characters who is the most human ironically.
Tsubaki is ready to kill anything that doesn't stand for her "justice" so she's a villain in my book, hence why I hate her.
