My in-laws were outlaws -- actual outlaws in one case, metaphorical outlaws in the rest. Either way it ended poorly. The actual outlaw, my brother-in-law, was a convicted fraud felon. He bilked people by selling them a "business opportunity" that didn't exist. But, like family members do, my husband and I supported him as best we could after his arrest and conviction. That's the right thing to do for family. You provide them with unconditional love so even when they screw up, you stand by them.
But when he attempted to perpetrate a fraud against my mother-in-law by tricking her into revoking Power of Attorney from the person she chose and making him her Power of Attorney so he could control her money, we could no longer love him unconditionally or otherwise. We had to sever ties. We even had to take legal action to undo the harm he had done to his mother.
