I agree with those who say they aren't going to judge any of it. Unless you are inside a family, you can't know what's really going on. Younger women are accused of gold digging as if money and only money is all a younger woman could possibly want from an older man, but sometimes there is real love there. If that's the case, the man got many years of true love plus sex (presumably) and maybe housework and other wifely benefits. Likely she is also doing some caregiving to an elderly man which in my book qualifies a person as practically a saint (as long as they do it with loving attitude). There is the opportunity she lost to marry someone else or focus on a career, so she technically has every right to try to maximize her own nest egg from what she inherits from her husband. Technically, if his Will is written that way.
Morally might be another matter, and especially if, as a person ages and becomes confused, they are manipulated into changing their Will. I have seen this happen. Not all gold diggers are young; an 80 something woman stole an 80 something man from his 80 something wife, where they'd been married for decades, got him to change his Will completely disinheriting his now ex-wife and leaving everything to the new little octogenarian hussy, then in 6 months he died.
The moral of the story: If you know for certain you want your children to inherit your estate, put safeguards in place against this sort of thing. What safeguards I don't know, that's for lawyers to help you with. It's a fine balance between what I want today and what I will think I want when I'm older and maybe don't have all my marbles. My advice to children is to be nice to your parents and not give them any ammunition to be convinced by an outsider to change their Will, and also stay involved and on top of their affairs.
Another case I saw a distant cousin began cozying up to the 80 something aunt and trying to convince her to change her Will but the nephew, who was her Power of Attorney, caught wind of the proposed change and was able to stop it. They went to court. It turned out the old lady only wanted to stay in her home rather than go to a facility, and the cousin was trying to convince her that the only way to do that was to disinherit the nephew and turn it all over to him (the distant cousin). The nephew had suggested she would be safer in a facility. Upon close examination by the Judge, the old lady admitted she trusted the nephew more and actually wanted him to remain in charge of her affairs, but only wanted to stay in her house. Thus the nephew agreed, she got in-home care, and the cousin? Vanished. (I am not even sure he actually was a blood cousin; there were suspicions he was an opportunist acquaintance. We have seen neither hide nor hair of him since.)
Moral of the story, stay close to your elders and make sure you are meeting their needs and wants. Be alert to this kind of manipulation early and nip it in the bud.
So in this case again, I can't judge. I don't know how the children behaved, how the wife and husband were behind closed doors, etc.
