How do you feel about characters who refuse to kill?

I found one thing I like about Ange from Cross Ange. She's okay with killing. That's one of the reasons I think she's a pretty relatable protagonist. She obviously killed some humans when she blew up those ships. Killing humans in the world of Cross Ange is okay, since most of them are bad. And even though a society like that is the result of endocrination and misunderstanding, Ange doesn't care. She reliezes that some peoples lives are simply worthless. She totally won me over when she said "Let's destroy this bullshit world" I also will say this...



Light Yagame was completely just in his actions... In fact, I'd say he's the greatest hero depicted in anime... not saying he's the greatest character, but he's the character who's perform the greatest act of good for the world ever depicted in anything ever. He was a hero to the entire planet and used his gift to make the world a better place... not by using the only way he knew how... but by using the only way possible to bring peace upon society



There I said it... if anything, the people trying to stop have literally been trying to stop the only solution for the worlds problems. At the end of deathnote

Spoiler:

He's killed... and I said "well, there's goes the only possible method of peace and tranquility in this world, So let's give these officers a round of applause for returning the world to a violent war torn hellhole. Especially you L.. how you hypocritically used a human as a test subject to understand Light better

This makes me realize something.... not killing is for retards. Now... in Trigun and Rurouni Kenshin there's a good reason... they have psychological scars and problems relating to thier past which effects thier morality on killing... it actually makes them interesting. However, in Kurau Phantom Memory we don't get this... just an idiot afraid of killing (I still loved that show)



To me.... I feel that if you're going to have a character like this, they NEED to have a tragic backstory which effects their desire to never kill. Edward Elric... you're awesome, but you're also an idiot. Without a reason why these characters never kill, you get idiots blinded by dumb idealism and not using logic.



So there's my opinion... it could be intersting but only if the characters has been through some serious shit like Kenshin has... otherwise, you just have a dumbass who's overly sensitive.
