What is Unbearable to Legitimacy

Epistemic status: provisional.

In my notes for my review of Sharon Rawlette's Feeling of Value, I noted that it is possible to feel pain which is unbearable, but which neither ought to be, nor ought not to be.

The unbearability causes (in the realm of "is") a person to react against the pain, but that does not mean that the pain really should (in the realm of "ought") be acted against, nor that they believe that it should be acted against.

But what would it mean for legitimacy itself (God himself) to find something unbearable? It would mean that it ought not to be. Legitimacy itself would be unable to accept it -- this sounds exactly like it really should not be.
