becose bad guys are way more interesting characters than good guys, (what made the guy bad?, why is he doing this?)also the bad guys allways look alot cooler than your avarage good guy.
As for gaming where you play either the good guy or bad guy (RPG's mostly) the morality usually affects gameplay aswell, if you are playing as bad guy you will rob&kill people for money/other items when as a good guy you practically give away your stuff for free to other insignificant people of the world (poor people,beggars)
