“Humans aren't defined by death, and they're not defined by what they lack. They're defined by their connections.”

“Your life is defined by death, and each time you face it you grow stronger. You learn more, and feel more. It sounds stupid to say it like this, but not dying makes you more alive.”

“APD is primarily defined as a lack of empathy,' I said. I'd looked it up too, a few months ago. Empathy is what allows people to interpret emotion, the same way ears interpret sounds; without it you become emotionally deaf.'It means I don't connect emotionally with other people. I wondered if he was going to pick that one.''How do you even know that?' she said. 'You're fifteen years old, for goodness' sake. You should be ... I don't know, chasing girls or playing video games.''You're telling a sociopath to chase girls?”

“Feelings aren't good or bad. They're just weak or strong. Love, for example, is weak: someone loves you, you love them back, you're happy for a while, and then it fades away. But if one of those lovers betrays the other, then you have a real emotion - then you have something powerful, something that leaves a mark you'll never be rid of. Betrayal is the most delicious of all, but it takes a while to set it up, and fear can be just as intense if you know what you're doing.”

“Fear is a ... it's a weird thing, when you think about it. People are only afraid of other things, they're never afraid of themselves.”

“I've been clinically diagnosed with sociopathy,' I said. 'Do you know what that means?''It means you're a freak,' he said.'It means that you're about as important to me as a cardboard box,' I said. 'You're just a thing - a piece of garbage that no one's thrown away yet. Is that what you want me to say?''Shut up,' said Rob. He was still acting tough, but I could see his bluster was starting to fail. He didn't know what to say.'The thing about boxes,' I said, 'is that you can open them up. Even though they're completely boring on the outside, there might be something interesting inside. So while you're saying all of these stupid, boring things I'm imagining what it would be like to cut you open and see what you've got in there.”

“Hello, Kanta. They're saying interesting things about you on the news," she said. "I wondered if you'd survived.""He didn't," I said. "I killed him."Silence."I killed Mkhai, too," I said. "Tens of thousands of years, gone in the blink of an eye.""Why are you telling me this?" asked the voice."Because you're next," I said. "I'm the demon slayer. Come and get me.”
