I don't think it's a conscience that's bothering him. I think she owns the house they live in and if she has to go stay permanently in a home she will have to sell the house and he'd be on the streets. He doesn't just lie constantly, he's also a thief and assumes everyone else is also. I learned the hard way that if I lend him anything at all, I will never see it again. Additionally he blames his temper issues on Obamacare. He never thinks he's wrong. I'd stake my reputation on the fact that this guy is a psychopath.
