Most people would understand what this monster was going to do. He was going to rape her and then rob the place for everything he could take. She intended otherwise.
My only comment in this is that the revolver she should have had was at least a 38 that could shoot +P loads. A 357 Magnum revolver would be better because it could shoot 38 Specials, 38 Special +P and 357 magnums.
Had these been in the weapon, he wouldn't be wasting a hospital bed, breathing oxygen, or IV fluids, etc. A mortician would be embalming him.
You might be surprised what you find.
