No such thing as an 'extra' nail in the coffin. If the decision was made, it was made. What you're implying (probably without meaning to) is that Kay may have already kinda made up her mind to maybe leave, but maybe sorta might've changed her mind, except upon learning that along with everything else he might possibly have killed a NYC cop some 8 years earlier (since he did state it was false when presented with the question) really, REALLY did it for her and that's when she knew she was really, REALLY going to leave, no kidding around.

Not the case.

So again, Kay's presence at the hearings did nothing to either damage or repair her marriage to Michael. It did nothing to enlighten her further as to the kind of life she had married into. It was over before she ever set foot in the Senate Chambers.

Again, if that's fun to imagine then it is your right to enjoy yourself. But I would guess she had already come to these feelings long before. An added question of did he kill a police officer, to which he answered no, would not have done anything to further Kay's horror at that point. It was not going to top having had machine-gun fire that you know was meant for your husband come in through your bedroom window in the home you share with your children. In fact, by the time of the hearings she may have been completely numb to anything she learned about Michael, having already aborted his son and making the decision to leave him.
