"Have I killed? Well… I've defeated heartless and nobodies, so I guess I've killed." Sora said, looking down at his feet as he walked. Kratos said nothing.
"With a key."
"Yeah, the keyblade."
Everything was silent for a moment. Sora looked over at Kratos.
"They're like cockroaches, kind of." Sora said quietly.
"Who?"
"The nobodies and the heartless. They always come back, it's irritating."
"That is not how you kill a man." Kratos said.
"Oh no, wait. I wasn't…" His voice trailed off as the large man walked away.
"Hey, where are you going?" He asked, following Kratos.
Kratos slammed the man's head down on to the ground and sat down on the man's back. His hands, one under the man's chin and the other on the top of the man's head, held on tightly as he yanked upward, towards himself. The man screamed and Sora's heart leaped in his chest.
"Kratos! Stop! You're going to kill him!" Sora yelled, and grabbed the man's muscular arm in an attempt to pull away Kratos' hand from the man's head. Kratos responded by shoving the young man away, knocking him to the ground. He gripped the man's head again and jerked upward and, again, the man screamed in pain. He flailed in a weak attempt to get the Spartan off of his back and Kratos responded by slamming the man's head into the pavement again and jerked upward again, twisting. The skin on the man's neck pulled apart and blood soon came rushing out, covering the white floor. Finally, with another twist, the man's head popped off.
Sora could only stare in shock.
Kratos slowly stood up and turned around to face Sora. He walked calmly to the young man, holding the poor guy's head by his hair. He kneeled down in front of Sora and shoved the man's face into Sora.
"This is how a man kills." Kratos said coldly.
Sora's eyes widened as he stared into the dead man's face and let out a terrified scream.
… I was walking and listening to Make a Man Out of You and thinking of when Kratos rips off Helios' head. Then it somehow turned into this.
