Well, morality is a bit hard to discuss with someone who they themselves refute having any. However, I believe that if you address some of these points, you will indeed realise that you have a sense of morality about you, although you may not realise it.

*You see a stranger, shot and bleeding on the street, do you help him?
*An old enemy of yours needs a blood transfusion or he will die, will you give it to him? ( You yourself will only suffer minor nausea)
*An old woman infront of you, 80+ years of age drops $20 on the ground, and doesn't notice. She is dressed is raggy apparel, give it back or keep it.

Answer these, then we can proceed.
