Should men protect their wife while no fault divorce is a thing?

Rather simple concept.

If men have to be ready to die for the wife, why should the wife opt out of the marriage for no good reason?

One can argue that wives have childbirth risks, but then again, they are legally free to kill their child, no matter what the man wants. So they never have to have the childbirth.

So should the men be free to choose their own life also and opt out of protection duty?
