It would have. They wanted him to. The settlement money is hers. If he relinquishes guardianship the money goes with her.
Does he have anything to gain from continuing this battle? Blowing money on attorneys seems to be of no benefit unless there is still a lot of money left.

Apparently not true here.

So much for the 'for better or worse'. She is, in fact, not dead. Yet.
Is it possible that he really is doing what he truly believes his wife would want?
