I have noticed how Disney villains always had to be responsible for their own deaths. The good guy can’t straight up kill them. The preferred method has been to have them cause their own fall from some great height. This also conveniently allows them to disappear from sight, so the young audience is spared the ugly after image.
I am happy that YouTube user ChiefBrodyRules has put together this super cut of Disney villain death scenes. (mostly deaths, some are just falls.) While not specifically comedy, there are some funny moments added in, usually provided by the sidekicks. Some villains are a little ridiculous to begin with, so humor works better with them. Others are portrayed as truly fearsome, so it’s more appropriate to keep their deaths serious.
