^^ Have u missed the example of Masab Bin Umair (RZA)
I believe that he was struck down by others, not himself?
The accounts I read of his martydom at Uhud say that he was killed by another man. T
While it was very likely that he would die when he went to pick up the banner, , it wasn't certain. At any point until the final sword blow that brought him down, he would have remained alive had his enemy chosen to show mercy on him.
With suicide bombing, even if the person the bomber is attacking decides not to land a killing shot or blow on the bomber, the bomber still commits the action that kills himself.
