Sinning, as Jesus and the church say, is good. Turn or burn Christians.

[Greatest I am]

If I make the claim that there is no sweetness in the color red, I can't then wax on about the sweetness and sourness of red as a yin and yang.  

You, GIA, are providing the demonstrations that you see evil in cooperation, and also, fwiw, good.  Greater good, even.  Your two opinions on the subject cannot be true simultaneously because they are directly antithetical claims.  Either there is lesser evil in cooperation, or there is no evil in cooperation.

Pick one.  

I don't care, I think that you're wrong either way, but it will be an improvement from the point of view of logical discourse, which is what you believe your position to be, and there's no need to argue your good and bad making theory to explain what the concept of sin is about because sin is metric neutral.

In your telling, sin would refer to the urge to mate.  If that's the thing that makes us engage in all of our bad thoughts, if that's the thing that compels us to competition rather than cooperation, that's sin.  It's intrinsic to human beings as a consequence of heredity.  Not the competition, not the evil, the thing that compels us to it.  As suspected, you do accept the concept of sin, you do think that there's something about people that compels us to evil - you just use a different word for it, and have prudish ideas about what that thing is.

Please, less psychobabble.

If I want a shrink, I will find one.

As to the evils of cooperation, if we cooperate all the time, we would never know who is the fittest.

Why do you think we do sports?
