- "I see the darkness of my soul and the fading light struggling to live in the toxicity of my nature. I feel cruel and heartless, but happy to kill your loved ones, your dreams, your future, and, most of all, YOU. My pain isn't limited to me, I shall spread it to you... go to sleep!"
- "The marks hurt, but they could be worse. It's not too bad, they remind me of life. Cruel, unneeded, and purposeless. Death is a gift, life is a curse. It's time for me to give you a treat, GO TO SLEEP!"
- "Jeffrey? Jeffrey is dead, my friend. You can call me... Jeff, the Killer. And, as you can see, I'm a lot happier."
- "Sometimes, what doesn't kill you makes you wish it did..."
- "I'm so sorry, brother..."
- "Lock me up, chain me down, but you'll never turn my smile into a frown."
- "Quiet down, my friend, it's nap time... Now go to sleep~"
- "You'll either die a hero or live long enough to see yourself become the villain."
- "I may be twisted, I may be crazy, but remember in reality we are all the same. Equal. You are just like me, no matter what you tell yourself. I am you, and you are me."
- "Smile, don't frown, when life makes itself difficult."
- "I didn't mean to kill everyone..."
- "What is normal? Nobody is normal... People try but we're all monsters, we're all crazy... Some of us just don't know it yet and others try to hide it."
- "You don't have to be a killer to be happy watching people (Kenny) die."
