"Natural karma"?

So if you see someone get on your bike and ride away, laughing at you, you're just gonna stand there and do nothing?

"Oh well, 'natural karma' will catch up to them eventually. He must need the bike more than I do, let him have it. Poor guy probably had a terrible childhood, maybe I should offer him my wallet too. Hey! Wait up! You need a few bucks bro? A girlfriend? How about a place to stay?"
