I usually rooted for the bad guys when I was little because “If I didn’t like them, who else would?” I also usually liked the deformed, unpopular good guys.
I often root for bad guys, which maked people think Im evil.
I root for bad guys when the good guy(s) is/are a (bunch of) whiny brat(s) like in most anime and some video games.
Also the original Power Rangers generation ended with the team blasting off again into deep space for the last time after getting beaten or something.
Also also DOH!!! ::doh::
I root for the good guys, just because you guys are making them out to be the bad guys. 
Belated Welcome!
