Women are capable of many things and some excel at being lowlifes. Perhaps she is worse than he is just more discreet. For example a stay at home worthless drunk as there are plenty of them depending on housekeepers.
We will never know for sure.
In an interview with the New Yorker magazine five years ago, Gibson said: 'There is no salvation for those outside the Catholic Church. I believe it. Put it this way. My wife is a saint. She's a much better person than I am.
'She's an Episcopalian, Church of England. She prays, she believes in God, she knows Jesus, she believes in that stuff. It's just not fair if she doesn't make it because she's better than I am. But that is a pronouncement from the chair. I go with it.'
That would be a little tough to live with, especially when he's a drunk to boot
What is reassuring is that at the Day of Judgement, we will all know.
