Monsters don't care about hurting people.

[Of course it's reasonable to be upset if you turn into something that's not 'you' and hurt people you don't want to hurt. But even so-]

Monsters aren't sorry for making people cry. Monsters don't care. You care a lot, Ryoji. You care more than a lot of humans I know.

So you're human. No matter what your body is like, no matter what you've accidentally done, you're human. You can't change my mind.
