I think how you feel is common. Consider a baseball team....how do you think they feel when they win and the other team loses? The way you describe yourself sounds like you are just responding to the social and cultural norms which are nurtured and applauded within our society. To be a winner, someone must lose and to be a winner is what most people secretly want. Like another poster mentioned, the mere fact that you care about this indicates you are not a heartless, soulless sociopath with no empathy.
