Amy wakes up with a knife in her back. After several frantic minutes, she resorts to slamming a door on the handle, and then begins painfully inching forward to try and slowly pull the blade out.
The female Deader initiate committing suicide on video in the beginning of the film. She shoots herself in the head, and then Winter (rather erotically) breathes life into her corpse. She revives and climbs off the bed, revealing the massive hole in the side of her head and her hair matted with blood. Even Amy, who is no stranger to the dark side of humanity, is thoroughly disgusted.
Pinhead executing Winter and his followers with his trademark dismemberment by chain trick and a single chain for his Deader Initiates respectively is the most gruesome moment in the film. It's also strangely satisfying, considering what Winter and his followers did.
