Morality is nothing more than an instrument to prevent us from destroying ourselves. I.E. prevent hitler like characters from killing us all. By aspiring to notions of good and evil, and right and wrong, we prevent ambition, ego and our inherent desire to control from destroying us.
No, the morals don't do that, the enforcement of laws do it. Morals are just ideals on which our laws are sometimes/often based. Without laws and enforcement, morals ain't shit.
Did morals prevent Hitler from killing people? If you think so, you should join forces with James R!
