Kieran will probably try and be friends with everyone lol, even the slightly scarier characters - his ability means that he's pretty good at telling when someone just looks agressive as opposed to them actually being violent. He has more info to go off, so he's a pretty decent judge of character, he has pretty decent instincts of when someone wants him to stay well enough away though, and he sometimes gets a bit in his own head and forgets that reading emotions isn't a normal part of social interaction for most people - which can be off putting to say the least. He pretty much always thinks the best of people because he understands where they're coming from - whether for better or for worse. Make of that what you will :)
