Whats wrong if I go on a killing spree? Whats wrong if I begin doing whatever my animal instinct wishes? People will dislike it, it will cause pain to them (and eventually to me as well (there exist Laws and order)), Right? But Why is it that I (and every other people) should have pleasure but not pain? After all pain as well and pleasure are the state of minds, Why should we ever consider one to be better than the other? Why can't we be in deep pain but yet like it that way and be happy (I think some monks have already achieved this)?
