At age 4, I can distinctly remember watching cartoons where the villain captured the beautiful heroine.

1) The villain is much more interesting than the hero
2) The villain seems to have much more fun than the hero
3) Why does the villain want to kill the heroine?  Surely he could find some better use for her?

Of course, being 4 at the time, I sort of figured helping around the house or something like that.  It took me to puberty to realize the REAL fun one might have.

So yes, "villain" is clearly the right answer for me!
