On their own, I think, men would do good. Without desire, without the need for pleasure or hunger, men would always choose good because it is the smart option. This is why God introduced women. Women fill men with an evil desire, the desire for a human to submit sexually for their pleasure.

Why? So imagine, hypothetically, the perfect good. It would be an almost still, boring thing to be perfectly good. Sex is the act we need that brings us into an evil setting, from which if we overcome the poison of it we have a journey to doing the true good; overcoming evil. That said this proves Solomon was right, and women were created for and produce only evil, even just in your own mind's physical calculations for desire.
