Given the Christian worldview, it would be a logical idea to have a designated executioner who sends people to heaven at a particular moment when they're deemed to have a pure heart and absolved of all their past sins. The executioner would be sinning, sure, but only for the sake of ensuring as much people as possible get to receive eternal salvation.
However, natural selection is a stronger force than logic when it comes to decide which religions survive, and a religion that accepted this consequence would get wiped out pretty fast.
Are you suggesting Christians should designate one very special guy to place the burden of all of their sins on so that they can confidently attain eternal salvation?
