fool me once, shame on you. fool me twice... has a friend's newly discovered past ever bothered you? like you've become good friends with someone and then you find out about something that they've done and you realize that you really can't be friends with them anymore? i mean, nothing as serious as say "i used to be an axe murderer" or anything. but maybe if they got caught stealing something big, maybe credit card fraud, maybe cheating on significant others, that kind of stuff. are things like that ever big enough to dissuade you from your current path of positive friendship? will the fact that a friend has done something that violated your moral code, is that enough for you to write them off?

rehabilitation is great, but if they've done it before, couldn't they do it again?
