The logical consequence would be that I should get absolutely every little piece of self-gratification I can get before I die. Forget the eulogies, forget my kids, forget my lasting impression upon the entire human race for milleniums to come...it's all just a pile of stinking manure if I'm dead, and never to be again.
I don`t think you have a choice... There are basically two kinds of people in this world: People that have a conscience, and people that don`t have a conscience. If you don`t have a conscience, if you have a severe personality disorder, like psychopathy or extreme narcissism, then you can indulge in self-gratification all your life, and die a happy man. But if you are normal, if you do have the capacity to feel guilt, shame, etc, then you have no choice: You have to follow certain absolute ethical standards, cause if you don`t, you will end up feeling like crap, and on your deathbed, you will feel that you have failed in life (which must be the most horrible feeling). (and im not talking about biblical rules, but what we all know is right, such as "abstain from" rape, murder, adultery, violence etc). So I don`t think you have a choice in the matter. Hope that makes it easier for you...
