Nick in Bone Tomahawk

This deserves a spot on our list because it’s got to be one of the worst and most horrifying horror movie deaths ever.
In perhaps the most famous scene from this extremely gruesome movie, Evan Jonigkeit’s character Nick is among a party of Westerners captured by a tribe of inbred, cannibalistic Native Americans referred to in the movie as the Troglodytes, or cave dwellers.
If you’ve seen Nick’s death scene, it’s surely burned into your memory. The Troglodytes strip Nick naked before scalping him and shoving his scalp into his mouth with a rock. While he’s still alive, they visciously bisect him. Then they eat his body. The sound of Nick’s screams, plus the scraping sound of the sharpened tool the Troglodytes use to perform the bisection — a bone tomahawk — is absolutely sickening.
