Because it's more complicated than 'good' or 'bad', right?

[Chuuya at age 15 can understand that much, at least. He still has some growing to go before he's the same Chuuya Magnus knew, but there's the start of that kind of growth in him.]

It's really easy to just say 'this person is bad, let's kill them' or 'this person would kill me, so I'll kill them first.' But that's how we get five deaths in one week, yeah?
