Do you donate to any charities? Assuming "yes", I would think it makes you feel "better" in that you're doing something for someone/something that has no idea who you are/what you've done.
I have to assume ARod has some of that in him. Or, even if he doesn't, he has to know that someone will say "That's pretty nice of him" and, if we're to believe what's said about him, he can use that positive affirmation thrown his way.
