The internet is loving up theories at the moment, and an eagle-eyed Redditor pointed out something pretty creepy:
Willy Wonka knew those children were gonna die in his factory.
Oh, so you want proof now? OK...
Look at the famous scary tunnel scene, after Augustus Gloop is lost in the tube.
The remaining survivors get into a boat...with no extra seats.
Therefore, Mr Wonka knew he wouldn't need more seats beforehand.
Then, once Veruca and Violet are gone, they ride through the Wonka Wash.
There are no extra seats on this vehicle either.
So...it's kind of like a tasty, chocolatey Hunger Games.
Willy Wonka: cold-blooded child murderer. Have a nice day.
