If there is no enforcer, then I would assume you don't believe in an objective morality either.
On the contrary, if morality is objective, there is no need for an enforcer. It would simply be the case that one sort of action would be better than another.
I do believe that there is an objective aspect to morality. It's not that morality is itself objective (it's a cultural or conceptual construct) but rather the standard by which one may evaluate values for their goodness and desirability is objective.
That means, anything that you can arrange with your own conscience will be an adequate behavior. Noting that our own conscience is dynamic and can be altered (making us apathetic to some suffering or wrongdoing), and considering our conscience to be a mere evolutionary-emotional shackle that keeps us from unleashing our true potential, it would be rational to maximize profits while paying little attention to that irrational emotion.
This is not even close to my view. I don't think that conscience alone is sufficient to weigh the goodness of values. Conscience is merely a tool, albeit a useful one, but is only as good as its "programming" -- the moral ideas that one has adopted.
And I have no idea what you mean by "our true potential". Our true potential is wisdom and good character, not money, power, status, fame, etc.
In a world without God, I would argue, it is indifferent as to how you seek fulfillment
The "world" may be indifferent, but that does not mean that it doesn't matter to one's life how one seeks fulfillment.
If there is no God, why should one way be "better" than the other?
Because one is a human being with a nature that determines one's needs and highest potentials. It is possible to fail at being the best human being that one can be.
After all, emotions are just emotions - controlling them to provide you with the maximum feeling of luck and happiness (fulfillment) should be the sole purpose of existence.
Not my view. That is far too subjective a concept of happiness.
I know this may be a ridiculously stupid line of argumentation, but that's what I look back at my Atheist life at: you're going to die when you're 100 years old anyway, so why not enjoy life to the maximum and frick the consequences (and anyone else while you're at it)?
If that is what you truly believed as an atheist, you were clearly messed up, but you shouldn't project your personal failings onto others.
Okay, your argument seems to boil down to this: it is rational to achieve one's "true potential", this being traditionally "materialistic" values such as wealth and power, and morality only stands in the way, so avoid morality.
However, this begs the question of just what one's true potential is. If one's true potential includes other values, such as wisdom, then it isn't necessarily rational to be careless about morality. Morality may be a means to one's true potential, instead of a hindrance.
