Did the chr-stian hero defeat “sin?” Well considering that crime throughout the world is at an all-time high that would be a no.
Did the chr-stian hero defeat death? Well considering that 105 people die every minute that would have to be a no as well.
Did the chr-stian hero defeat the devil? I am not able to provide statistics on that one, because chr-stianity created the devil, and it only exists in their own imaginations. I guess it doesn’t really matter if an imaginary character defeated another imaginary character.
So because people commit crimes every day; and because people die every; and because there is no such thing as a devil, the answer to all three is no.
