It all depends on which story you have heard and believe, I have heard he was seriously wounded and not survive treatment, so could be classed as a mercy killing like some troops did in Falklands. But nothing was mentioned about that at the time.
You might know enough about yourself, no one is arguing about that, but to make a statement about how you would act under wartime conditions is just stupid, you have no idea how you would react, let's hope you never have to find out.
