I don't mean just seeing something nice and wanting to have something like that. Some people would not mind doing anything to take what belongs to another. Why do we have people like that?
It is mainly because there are people that is born with greediness. Selfish people can't accept on the state they are living and jealous of other people, of what they are and what they have. They have no choice but to take what belongs to others since they can't have it on their own. They should learn how to be content and find other ways to be happy.
