Again, all the way up through the early/mid 20th Century, there were certain Western wrestling styles that contained (little used but well known) techniques which could easily result in serious injury or death. Heck, the Fireman's Carry (Kata Guruma) was only recently fully banned from Collegiate style wrestling because of its propensity to break necks and cause permanent paralysis, even from the kneeling position, never mind the Back Heave (Ura Nage).Again, not intended as a killing art. Wrestling and boxing in modern-day parlance have evolved as simple sport, not self-defense (regardless of how good they are when used in that sense). I'm not arguing that any of them are not martial arts. But with regard to 'killing with your bare hands' as the OP queried, boxing, wrestling, etc, are not that. They have no killing techniques that are in their systems. Yes, you can certainly kill someone if you're a good enough wrestler. Or, for that matter, just a really bad dude, some kind of serious street fighter. But that wasn't the question.
I know most people don't think about it, but Catch as Catch Can, for instance, had (has) all of those "dump 'em on their head" throws and a lot of the same sort of major joint lock which, if taken to completion, could lead to joint damage. Everyone remembers "Strangler" Lewis and Frank Gotch's "Famous Toe Hold."
