Right? I feel like everyone here in comments are missing this exact point.
They're living breathing thinking humans who are also jocks. Not only they are not dumb zombies, they're physically strong. It would be too risky to try going against them head on. It's a suicode mission.
The only thing I could think of maybe lay a trap and kill indirectly. Like when Youngwon "forgot" to turn off the gas.
That wuss saying to kill them back would probably pee his pants when he sees the other group first and end up getting killed instead. Easy to say to kill someone but extremely different to do irl
