In the movie The Santa Clause, one becomes Santa by putting on the red coat after the death of the previous Santa. Even ignoring how morbid this premise is on its own, it’s possible that there’s another even darker level to the story. When Scott Calvin shows up at the North Pole as the new Santa, not only do the elves not appear surprised, they seem happy to see him and not at all upset about the Santa he replaced. And furthermore, at the very beginning of the movie, we see an elf standing with a crowd of children outside a toy store near Scott’s house. Why would she already be there if she didn’t have some sort of prior knowledge of what was going to occur? This leaves me no choice but to conclude that the elves not only hated the previous Santa but actually orchestrated his demise.
tl;dr: In The Santa Clause, the elves totally murdered the previous Santa.
