"I will deliver death swiftly to you... you have my promise." As dire as the words were, they were delivered with a friendly smile. Guilt was far from his conscience. It was a reasonable request. The man knew where the street was headed, why not get there a little quicker and evade the suffering? Even if it weren't, it was just another mortal's life. The man could make his own decisions. If he doomed himself, that was not Loki's problem.
