Instinct deep in the human psyche surfaces when a predator strikes. A psychopath selects soft targets and begins slowly.

The women didn't start this action. They defended against it. When does defensive collaboration become entrapment? Should they have waited for a murder? Was there a murder they missed, a victim they couldn't save?
