I saw it awhile ago, maybe mid-2000s. I think it might be a spin on The Hills Have Eyes?
One scene has a womans eyes taken out and she is raped by monster-looking beings. Then she escapes and is walking on a road when she hears a truck drive by. Thinking shes rescued, it turns out to be the monsters!
Another scene involves a woman sheriff or something. She gets tied up in a cabin and is attached to a stringed shotgun. The cabin is set ablaze and she has the option of shooting herself rather than burning alive. She chooses the former.
