Do atheists even need an objective moral system?

[pocaracas]

Where does this idea that morality applies only in a social context comes from? If my actions don't affect anyone other than myself, then are those actions beyond moral judgment? Do you really mean to say that a day I spend binge drinking and watching TV is morally equivalent to learning something new?

Morality is something more basic than our social behavior.

I guess we've come to the definition of the word: morality, morals...
As far as I see it, it's the right thing to do. Right in the light of better for the world.
If you do something that is of no consequence for the world, then morality doesn't apply.

If you kill yourself, you reduce the human capacity in the world, and force some one else to handle your carcass.... someone would have to do it eventually...
If you drink and watch tv, instead of learning something new, you're just doing some temporary harm to yourself... postponing your potential contribution to the rest of the world.
It's almost impossible to find a situation where anything you do affects you and only you.
