You don't need to look at their eyes, but people have a tendency to look at the opponent's face, and Chara's nonthewiser.

They can't use it on their own, that's the point. Otherwise they would have killed the timeline and amped beyond Asriel's level.

Betty has teleportation and time isn't in Chara's favor. Even if he amps himself to insane degree, Betty can just sit there while Chara's incaped for 24. She doesn't need to kill them, in fact, killing them wouldn't do anything.
