Why are people so freakin nasty?

theres never one reason for these kind of ppl, perhaps its a self asteem thing who really noes. Many might actually think they diserve power because they are rich, pretty etc they think they are better than ppl because of a talent they might have, or they may not have any talents so they pick/har ppl with talent to make themselves seem cooler.they also may be out to impress somebody, there are alot of reasons y ppl are that way.
