All Elohim are rational.
The benefit of this is that grief never ends in blame. If nothing else, you are assured that the choice made was the right one, the rational one. He cannot beg a god who never answers to rewrite history, to take him instead. If it took her, it was because she was the one who had to be taken. That is how things are and how they must have been.
It cannot rid him of regret, of course. It cannot rid him of the desire for things to have been different, though it forbids him from dwelling on it. It does not stop him from thinking of all the things he might have said, if he'd known. It cannot prevent him from thinking how they might have said goodbye, a touch of fingers, a knowing look, closure.
There is relief in knowing that, as they were both Elohim, she would have wished for the same things, in the same muted, helpless, sensible way. Regret, acceptance.
If he walks in the rain, it is not for his own sake but for that of his servitors; they would be discomfited to see an Elohite cry.
