Why don't I feel the emotion to help other people?

Its not even human to feel compassion for other people. I hardly ever cry heck I cant even remember the last time I cried, but that doesn't mean I don't feel bad. I have been guilty about what you have just stated where someone had said something so touching and everyone else was on the verge of tears, while I was faking it. You cannot do anything about it until horrible things start happening to you and those you care about then you will start relating with other people in pain.
