Let's say, if you wanted children, and you were to have only one son, which of the following two would you pick.

Adam is a perfect paragon of virtue. He is intelligent, nice, studious, dependable, considerate, and is always available to help those in need. However, due to a painful innate awkwardness and lack of dimorphic traits has never been attractive to the opposite sex. He has tried to make himself appealing with little luck, though his failure has never made him bitter or resentful. Due to these traits and his inability to tell if someone is taking advantage of him, he ends up as an adult somewhat lonely and depressed.

Caleb is a callous manipulator who always ends up getting what he wants. He is incredibly sexually attractive to the point that it is impossible to ignore. He has hundreds of sexual partners, many of whom are taken or married. He ends up having a string of bastard children, all of whom he leaves the unknowing partner of his former lovers to raise. He is a pure narcissist, will do anything to further his goals, and has as a result become extremely well off socially and financially. He ends up completely satisfied with his life, as anything he has desired has never been too much trouble getting.

So if given the choice between Adam or Caleb, who would you prefer having as a son?
