Am I a Sucker for being good

Sigh... good people never have good ending! So am I a sucker for being good? Well, it does seem so to me! The things I do for people end up being stupid myself! People think otherwise and jump into conclusion that I am "the bad" guy. Sigh... at times like this, I wish to give up trying so hard to fight the battle. Fighting a loosing battle seems so discouraging. What can I say?
