Touko, why one person kills another person?

Touko Aozaki:
It happens when you feel towards someone exceeds your ability, Whether love or hate, the feeling that overflows from your container must be cleaned in one way or another. When this method becomes extreme, it becomes murder.

Mikiya Kokutou:
But there's people who kill without that.

Touko Aozaki:
That's not assassination, is slaughter. It only becomes assassination when people put their dignity and their past in a balance and removes one. Then loads the importance and the sin of to kill someone, but the slaughter is different. The one who dies is a human being, but the killer has no such dignity and ceases to be a human

Mikiya Kokutou:
Killing someone means to kill oneself. So, what is a serial manic?

Touko Aozaki:
It is what it sounds like. is a maniac that kills people, so it's like a natural disaster. Those involved are unfortunate.
