That's true, but at the core the reason Killua acted this way was because he learned from a different teacher who tried to make him do otherwise.

He would be. I'm totally expecting a "hoh... so you found out" type of response. I think he sees Killua pulling it out as a possibility but not an inevitability. Illumi will still be stronger than Killua as well I'd imagine, somewhere along the lines of Hisoka. Maybe Killua will manage to land just one punch as you say, since Illumi wouldn't expect Killua to try something so risky.
