You people confuse me. You see a mass-murderer, who terrorized two whole tribes, and you say stuff like, "He's cute, I like him" and, "Would." [I'm sorry, I just had to say that one...]

As an animus who doesn't realize he's going insane, he is a threat to everyone around him. One little annoyance or threat could send him off the edge, killing you in whatever way he sees fit. He's less likely to butcher those he loves, but there's no telling when he breaks again.
