@jeeprs,
I was playing the cynic, I suppose.
Yes, mankind has godlike powers, but I was talking of a man who alone has the power of a god. He has nothing to fear from other humans. He is supreme on earth.
The idea is what would man manifest in the absence of punishment/control from other human beings?
I think of the Caligula, but a mere man can be assassinated. What about a Caligula that was immortal? And if he were immortal, perhaps his attitude would be different. He would not have to rush. He would perhaps have the kindness that comes from security. But he probably would laugh at most of what we had to say, especially about morality.
I don't approve of this super-Caligula. But I think we should be honest about the power of the threat of punishment, and consequences in general. How much of our good behavior is simply prudence?
