I wish people would stop torturing this poor man. He obviously LOVED his wife & children and was a positive thinker-- who never give up hope that his wife would be well and normal. And he OBVIOUSLY was not secretly hoping that his wife would kill their children.....!!! It's not like he could predict the future and certainly was not expecting or thinking that the absolute worst scenario would happen....
If he could go back and forsee the future he obviously would NOT have left his wife alone with the kids, now would he? Surely he has gone through enough hell beating himself up with the 'what ifs' of the situation. God, it's not like he drove drunk and killed a bunch of people or beat his children to death or starved them. Leave the guy alone already. He's trying to live his life and do the right thing and he has every right to have a family... he seemed like a great dad, and he deserves the chance to do it again.
Remember that Andrea was not some helpless victim who was kept at home with a gun to her head. If she REALLY wanted to have more of a life outside the home, she should have SAID SO and maybe they could have come to a compromise. But there are plenty of women who DO want to stay home, and plenty of men who want wives like that... and there's nothing wrong with that if that's what they both want. So people need to get a clue and quit judging this guy. What's done is done and it's too late for that.... hindsight is 20/20.
That being said.. sure there may have been some denial involved.. no one wants to believe their spouse is seriously mentally ill, and he hoped that being with her children and being at home would help her be well. He probably did not know, or did not WANT to understand,, the extent of her illness. Also, she seemed fine sometimes. Mental illness can be very mercurial. So give Rusty a break. He did not intentionally wish any harm to his children!!
