What is the ruling on living with a relative who practices pedophilia?

Sodomy is a great abomination. Its heinousness increases if it is committed with minors. The perpetrator must be admonished and warned of the consequences of his actions. If he does not repent, he must be threatened with exposure and reported to the authorities for deterrence. He should not be allowed to live with others, and he should be shunned if that serves a benefit.
