I suppose we souldn't begin on this topic, we should first state if their is life after death, and if there is a difference between hell and heaven. Death sentance may just be an exciting trip to heaven, that's not really a punishment, everyone in heaven would be like "how did your material life end?" and he/she would say "Electrocution" making the others reply "Ooh respect man, you'll fit just fine in our society, unlike those wimps who did from cancer. Welcome to our order brother." And god would be like "U'r lucky you're electrocuted, I pitty those bastards who get reanimated, those poor souls."
So you see, this argument wouldn't be valid if we in fact have stated first there is an afterlife.
