Lots of people have been maimed by your method, but they did not die.
That’s not enough assurance for me.
As I said, if you are that incompetent you should be nowhere near the battlefield.
Also, if you’re so inclined, you could always fight to the death. Unless of course you are worried that your enemy would inexplicably and unreasonably be so determined to capture you alive in order to torture you to death. Possible, but a REAL stretch.
