An interesting view on morals

The last line of my previous post triggered this thought. I was debating the subject of morals with my good friend Jorge from Mexico. He believes that morals are simply an idea and/or concept that we convince ourself is existent in order to feel better about this place we live. Because in reality morals and altruism are non-existent. Being the realist Iam I took this into deep thought. We all know right from wrong, everyone from a little child to a grown man knows what is right and what is wrong. But what is moral and what is immoral, and if they are existent who is to decide? Same goes for right and wrong, in a sense. So is it good to have morals, because to have morals is to believe in them, them being the morals you came up with.
