Superman. Those tights are to die for.

Superman,invisibility is not a desirable trait for a role model

They are, not in the least bit coincidentally, incredibly similar characters. Both being based somewhat on Moses, of course, with most modern (non Jewish) writers more directly sourcing characterisation and symbolism between the two directly.

Both are socialists who still retain a certain degree of Patriotism without being nationalists. Both are at their best `hopeful' although Jesus is less directly concerned with concepts of Justice.

If one looks directly at only the gospels Jesus is a pretty good role model. If one also reads the acts he becomes less so and if one is at all influenced by the subsequent works of many of his followers, his value diminishes even more.

Superman, being a more recent character, is far less currupted. Although the far greater sum of source material acts as both a positive (more examples of positive behaviour) and a bad (more missteps as well). But ultimately those left in control of Superman have a far better grasp and understanding of the character than those who too command of the Jesus character and his initial ideals, so I'd say, functionally speaking Superman by a long stretch.

HULK SMASH

I am not sure either fictitious character can be a role model, don't role models have to be real people? Imaginary characterization are just renderings of ideals.
