If an animal gets its head stuck, predators will casually eat its meat without first killing the prey. This makes sense from their purely selfish point of view, especially as it provides a sort of short-term "food preservation".

Ducks have been documented engaging in necrophilic gang-rape.

Dolphins use literal waterboarding to rape.

Humans are just smarter assholes than other animals. Not worse or better.
