Depends on the person. Many people also feel great when they act like dicks. This possibility is just hardwired into the human character for everyone, and for some people it's a lifelong thing. Many are entirely indifferent to helping anyone. Many don't help anyone enough to know how they might feel about it.

I really think there are just different kinds of people in the world, and plenty of them. There is usually just as much aggression in social situations as there are good things, and that even from people who would never consider themselves aggressive or less than superlative in any way. We're a viciously competitive species, and it's often not enough that we're together, but we must compete; and it's not enough that we win, but someone must lose. We're genetically built to screw each other over, and that's at least as natural as helping each other or giving a damn about each other, if not more so.
