The poster (who I assume read the story) advocated killing the young man even though he knew he was unarmed and hadn't been charged with violent crimes in the past. I simply questioned this.
This home owner had no clue what the guys intentions were, and just by saying "don't hurt me, I need help" doesn't mean that's true. He could be saying that after he knocked the homeowner out and while he's raping the women of the house.
