Reply To: Is An Amalekite Allowed to Commit Suicide?

I dont know if a mitzvass eseh of michias amolek would be able to be docheh a chiyuv misah bidei shomayim (suicide).

You also should consider that for jews there is a concept of shchitah so he may have been mikayem the mitzvah as soon as he chops off his own head, or the idea of shchitah may only apply to animals but for people “death” is when the heart stops beating.
