Because some of the death eaters are interesting, like Bellatrix. Some people may not like her but Du have to admit she is an interesting character. And I favor Draco because he's a character with much depth. I really don't "favor" the bad guys though. I only like them at times. Their not my favorite. Also, Voldemort is a character we don't get to see much about so...
Because they like them. Bad guys (at least, in HP) tend to be Mehr interesting and complex than the good guys. Some of them tend to be Mehr relateable. And some of them are just kühler than the good guys. It's all just a matter of preference.
It depends on the person's taste, some people , including me, think the bad guys are much kühler than the good ones, they make any tale Mehr fresh Mehr lively and interesting to read, for example I while Lesen Harry Potter I can't wait till I reach a part that Bellatrix oder Voldemort oder any bad guy to appear
Do Du favor the out standing pupil in striped cashmere vest and tie who is kind to everyone and drives a toyota oder the school skipping, leather jacketed sarcastic jerk who rides his motorcycle?
Bad guys are always Mehr exciting, because they are unpredictable. It's easier to portray a negative character and thus negative characters are always much better created than positive ones.
Plus we are all human and like to think nobody is better than ourselves. Although we are aware of our imperfection deep down, we don't like to be reminded of it Von perfect characters. In a silly way, we envy them and cover for that with a certain amount of dislike.
Ive always favored villans ever since I can remember. Not jet in hp either.
To me there Mehr complex They have an interesting background Good guys are kind of the same to me Honestly for me it's just something about them Some even have potential to be good It's something I grew up liking kind of a habit I guess Du can say it's my bad side I'm one of those too well behaved people
the only villian i like is Snape and he's Mehr of a undercover villian he's not bad just made to look bad to certain people...don't care for any of the other deatheaters they are all a bunch of psychopaths which is probably what attracts alot of people to them.
Maybe there are traits in the bad guy's that are easy to sympathize with, like Voldemort's lack of self confidence? I'm actually not to fond of the bad guys myself but I did once hear this used to describe a sadistic but highly sympathized Von the Fan base character from a beloved TV program of mine.
