Suppose I had a cousin living with me. And my cousin starts unlocking all my doors and windows. He deactivates my alarm system. He starts hanging out with friends of people who have publicly stated that they intend to kill me. He takes money out of my dresser drawer and funnels it back to the same people. He prevents me from talking to anyone who would know the exact plans that my enemies are laying out for me. He takes all of my ammo for my guns. He leaves the house.
Soon, my enemies come over to my house and shoot my windows, and yell that they're going to come back later and shoot me. My cousin shows up and starts saying, "Here's what you ought to do...."
You're saying that not only should I allow my cousin to remain in my house ("For the sake of the family"), but that I should completely ignore his role in the attack on my house?
Ludicrous.
Focus, man, focus.
