Quote from Arcane Azmadi
I think you missed the point. Light wasn't a hero. He wasn't even an anti-hero. Death Note has the distinction of being a story told from the point of the villain. How many other manga have had evil buggers with god complexes who're convinced they serve a higher justice and that the end justifies the means for villains? It's a very common villain archetype. And yes, I don't like him much either.
Actually, there are many cases that are similar in games and movies to Light's situation. Light initially started killing off all the people who did crimes, and actually decreased the crime rate of the World drastically by his actions. He didn't really become a 'villain' until he started killing off law enforcement that was trying to capture him. Sadly I agree with the actions of Light and thought he was a very refreshing character to have. I feel similarly with Lelouche. Hence that's why my hated characters would be :
1. Suzaku - Code Geass (Hypocritical, and reminiscent of all the characters who go "it's wrong to stop war with war! Peaceful situations are the best! That's why -I'm- fighting you too! I mean c'mon, at least Lelouche and them aren't preaching peaceful solutions while fighting, they've made it quite clear peace doesn't seem to work. I just don't like the character because there's soooo many of these but they're usually the main leads.)
2. Sasuke - Naruto (... Puhlease... Emo/Inconsistency in how he's portrayed relationship and power wise. I can think of much better rivals for Naruto. Granted I haven't been into the series much since the time skip... 666 Satan did the timeskip and the character changes MUCH better.)
3. Onigiri - Air Gear (Must I explain?)
