And here is where we diverge. You believe that A is the finer death, because it is what your god asks of you. I believe that B is the finer death because it is pleasing to my gods.
While I respect the dedication those martys showed, they gave up, forfeiting their lives (as the bible tells them to). To face certain death, and take as many of your enemies with you as you can is pleasing to the gods, showing you are a brave warrior who fights to the death.
While getting in to christian heaven is based on gods mercy and your deeds and love on earth, Valhalla is home to only the brave and fierce warriors. Many good, loving people do not go to Valhalla, you dont get in on your kindness or good deeds (although that is part of honor). Odin wants only the strongest, bravest warriors, because when Ragnarok comes they will march from Valhalla and join him on the field of battle. To go to Valhalla is to train to fight the final battle of good vs. evil. As such, one must be a warrior who will fight to the death, not one who will quietly accept death.
