Oh, I have no doubt that you consider him a friend. He even considers you a friend! But he's really not the sort of person you want as a friend.

You see, we're not really all that different. He's hurt a lot of people, and his actions have even lead to people getting killed. Maybe not intentionally, but he was certainly aware that was a possibility. He likes to act like he could never be anything like me, but in reality? We're already quite similar.

I'm not saying he's going to kill you, or even that he'll get you killed. But he's nowhere near as trustworthy as you seem to believe he is.
