Chara himself had no experience with killing anything except for youma. There was that ONE time where he was ready to choke a Negaverser, but the guy just teleported away. Just POOF bye bro, like they weren't fighting at all. It was actually seriously curious.
"Yeah, yeah.. Annoying, a** kicking, gotcha gotcha. But you're not that bad now, are you, now that I think about it. Every Negaverse agent I fought, sans that one crazy a*****e general was all 'nope I'm out' and stopped fighting. Just go to sleep, m'kay. Take in his moment of peace you have before s**t hits the fan again. Need any more water? Or maybe.." He looked over at the cups of apple sauce still on the tray pushed off to the side. Naw, Chara wouldn't force him to eat it.
"Eehhh, just go to sleep. You'll be no worse than you are when you wake up, promise."
