The Nurse (Dead by Daylight) - Part 1
"Over the years, her mind had reached its limits, two decades of seeing horrid things that violate the eyes. Memories that are re-played every night. Being abused verbally and physically, by people without limits. Sally saw insanity from the outside, just to catch it herself.
Finally she could not take it any more and concepts of purification emerged inside her. She did what she felt was necessary."
