assuming that im sure heaven and hell ACTUALLY exist in the christian sense that you are probly reffering to (correct me if im wrong)
Then kill me however gruesomely oyu want, as long as i go to heaven in one piece, id do it.
But if however you got killed, you reflect that in the afterlife, like say, if i got my head chopped off, id walk around heaven/hell carrying my head and shit. So Then its a tough choice. Id rather be in hell with a bullethole in my head then be the biggest piece they could find of me, like a toe or something in heaven.
BUT ALL THIS IS A REAL BIG "IF". I dont believe in the christian beliefs on afterlife. Not anymore anyway.
