Light Yagami (Kira)

"This world is Rotten. Rotten people should be killed off to cleanse this world."

"He was someone who deserved to Die."

"I'm going to change the world."

"I am Justice!"

"Those who oppose God are Evil!"

"Wow, this is the first time ever since my birth that I want to hit a girl"

"I will erase him."

"L, Do you know? Shinigami only eat apples."

"The real battle starts now."

"She has to be eliminated."

"I am Kira."

"Looks are all that count."

"I'll make you trust me. And when you've told me everything I need to know, I'll kill you."

"You can't ever win if you're always on the defensive, to win, you have to attack."

"I've never considered finding that notebook & gaining that power a misfortune."

"The thing I hate the most is to trample on other people's good will."

"After I caught the current Kira, after that...I would become a Kira murderer? Do you see me as such a human being?"

"For murderers, there is no good or evil. I know that"

"Is he talking to himself...?"

"I won... just as planned."

"In every world, the God's always make the rules. You will fall before my fake rules, and for the sin of going against the new world's God, die."

"Long time no see, Ryuk."

"Rem, I didn't think you would go so far."

"I am going to be the god of the new world."

"There are a lot of stupid people out there."

"I'll kill him."

"I feel the adrenaline coming on."

"I must protect my fledging Utopia."

"If I play my cards right, I can work this to my advantage"

"But you know the saying 'playing with fire, and you're bound to get burned.' I'll make you regret underestimating L...underestimating me. "

"I'll need to appear full of confidence if I'm to take advantage of him."

"In your eyes lies all happiness for this new world."

"In the end, L is indeed the greatest detective on earth..."

"Our battle will be concluded, and I will begin my reign from the summit of victory!"

"Don't make me repeat myself."

"This is my win, Near"
