He finally snapped and they all felt the heat of Rudolphs revenge. He took out the others one at a time. Can you blame him?
There is only so long anyone, even a reindeer, can tolerate being laughed at and called names. I only wonder if he took them out in their sleep, because he seems like a sneaky bastard, or if he has a human hunter costume he wears when prowling for his prey. I suppose the answer is below.
“After everything was done, with all those in attendance, Rudolph got his gun, and had himself some vengeance.”
