[General] would have to be/would have to have been

[jiaruchan]

If John apologized to her, he would have to be crazy.

If John apologized to her, he would have to have been crazy.


Please help me understand whether the two mean the same. Thank you.

I'll be wondered if the sentences are correct.

If John apologized to her, he would be crazy.

This is the only appropriate way to say it in my opinion.

How about these two:

If John did apologize to her, it would have to be under duress.

If John did apologize to her, it would have to have been under duress.

This has a different meaning, John hasn't apologised yet and you are saying that he would be crazy to do so.

If John apologized to her, he would have to be crazy.
This woul be better written as: "John would have to be crazy to apologise to her"

If John had apologized to her, he would have to have been crazy.
This is correct but a bit cumbersome.

That's how you'd say it in the present tense.
He would be crazy to apologize to her. (He hasn't apologized yet.)
He would have to be crazy to apologize to her.

But the OP is referring to this happening in the past.
He must have been crazy if he apologized to her. (Perhaps he has apologized. If he did, he was, necessarily, crazy at the time.)
He must have been crazy to apologize to her. (We assume he has).
He would have to have been crazy to apologize to her.
If he apologized to her, he would have to have been crazy.

I prefer this version - the second of the original poster's sentences - over the first.

The following is possible, if indicated:
If he had apologized to her, he would have had to have been crazy.
But it's possible to leave out the second had here.

PS: I posted without seeing bhai's post. I think we agree essentially.
