Are human beens selfish?

Humans are selfish egoist, according to Hobbes. Humans are selfish because they almost all that time they just think about themselves. If a person is going to do something for you, they always think what they are going to get back out of it. The human nature theory of Hobbes says that although we were made in the image of God, we sinned and 'all our righteousness is like filthy rags'. We deserve God's wrath' or if one does not believe in God, we do not deserve an idylic life but, at best, to be alone by others. A person can be egoist if that person is seeing that someone is harm, if you are not feeling anything or no caring for that person, you are only think of yourself and not thinking about the other person feelings, that is beenn egoist and many humans are.
