-- Automatic new identity! Afraid you've left evidence behind that might net a conviction? Don't worry: If you murder Santa, he'll leave you his clothes, his physique and his hair color as well! This fat son of a bitch comes pre-Talented Mr. Ripley-ed.
"Yep, dead before you're 50."
-- Complete with getaway vehicle and remote hideout! You've got flying transportation and a kingdom of newly acquired servants to cover up for you. The best part is, it's in the North Pole; not just remote, but inhospitable! No extradition going on up there!
"Wow, this is awkward. Does it make it any better if I just admit all my crimes? I'm on a registry and everything."
Oh, but it's not all fun and games. For starters, you'd better learn to sleep with one eye open. When murder is made this easy and rewarding, you can be sure that there will always be a target on the back of the bright red suit that you can't take off. Being Santa means you have your own kingdom, clothes, vehicle, servants and nigh-omnipotent power. Who wouldn't want a piece of that? And in exchange, all you have to do is work one night a year -- a fixed night where you have to break into everybody's house and quietly rummage around their living room in the dark, thus giving everyone on earth a heads up and an easy shot at the king, all without ever having to put pants on.
"Ho ho ho, there can be only one!"
Fun fact: Near the end of the movie, Charlie (Scott Calvin's son) talks about going into the family business when he gets older. Get ready for The Santa Clause 4: PatriCider and Cookies.
