How could air bending kill anyone?

Tornado
Take away breathing
Let 당신 inhale not exhale and vice versa

...blow 'em off a cliff?

It's very simple.Airbenders could take the air out of your bodies and basically suffocate you.

I agree with the other people! Air is a very dangerous weapon. So only use it in emergencies! Lol!

make a really strong tornado

yes it can if 당신 have a vortex 또는 somethin spinin around 당신 and 당신 try to breath, 당신 can it sucks the air out of your lugs basicly so 당신 cant breath its like when your dog sticks his out the window and he pops his head back in sometimes...thats so he can get air,the wind is blowing to hard in his face to breath in 또는 out ,and it depends on the 옮기기 당신 use and were 당신 aim the attack.also what everyone else said

i agree with everything that was said here. most of the people think air the the weakest element because it works 더 많이 on a defensive way. that's why this element is so underrated.
but when 당신 think of the possibilities of being killed 의해 an airbender, 당신 will understand that air isn't weak, at all.
actually, i think air is the most powerfull and dynamic element. it's also my 가장 좋아하는 =)
and while 불, 화재 is the most overrated element, i consider the weakest

maybe firing some needles 또는 spikes with air xD

it can push thm off 나무, 트리 ,cliff,tower or
it can go soo fast 당신 pass out :3

it would suckout the air

의해 lifting 500 feet in the air and slamming 당신 to the ground.
