"I'm not just a tool for you to use in or…" — Mello Quote

"This world is rotten and those who are making it rot deserve to die. Someone has to do it, so why not me? Even if it means sacrificing my own mind and soul, it's worth it. Because the world... can't go on like this. I wonder... what if someone else had picked up this notebook? Is there anyone out there other than me who'd be willing to eliminate the vermin from the world? If I don't do it, then who will? That's just it: there's no one, but I can do it. In fact, I'm the only one who can. I'll do it. Using the death note, I'll change the world."

"Only I could do it! I was well aware that killing people is crime in itself! Yet at that point it was the only way to make things right! I thought to myself that someday people will come to realize this as much, and regard it as an act of justice! I had no choice but to act as Kira… it was the destiny given to me. I was chosen to renew this rotten world, to bring about true peace – a utopia."

"Humans are so... interesting."

"For me, apples are like cigarettes and liquor for humans. If I'm deprived, I go into withdrawals."

"Matt... I never thought you'd be killed... I'm sorry."
