If life was fair I believe it would be terrifying, which i suppose is a form of interesting. I know that a good chunk of the good things that have happened to me in my life only happened due to circumstances, and that I haven't felt the negative repercussions for most of the bad things I've done. And I'm probably a fairly normal person without much bad or good to speak of.
Then again, maybe it wouldn't be interesting at all if life were fair. The most wonderful, spontaneous things that have happened to me didn't happen because I deserved them, but it's not like I necessarily didn't deserve them, either. There doesn't really seem to be much correlation with good things only happening to good people anymore than the alternative. Maybe it's dangerous to expect life to be fair, not because you'll get hurt, but because you'll miss out? Like, sometimes it's comforting to expect that the guy who cut you off in traffic is going to crash for being reckless, because of karma or something. But when you start applying that sort of reasoning to yourself, you don't even necessarily see great opportunities, because you're framing the range of things that might happen to you based on your opinion of yourself.
