Objectively, yes. The woman is also being forced to perform an action under duress. Forcing what is essentially a rapist to use a condom is not subjectively evil, in this case. No person is required to participate in his own death. Self-defense, IOW. This seems like a no-brainer to me.
We must look at the situation objectively in order to understand it. This should not be a case of "situational ethics" or moral relativism, which is what is becoming the "norm" for most discussions of sexuality.
This is a no brainer! All orthodox moral theologians will concur. One may not commit a moral evil to defend one's life. This is basic moral theology.
If what you suggest were actual circumstances, then the spouse would be perfectly free to use commensurate force to repel the aggressor. This force would not be morally evil. The use of a condom is always morally evil.
So, if necessary, she could kill him before using a condom?
AHA!!!!She could shoot the so-and-so.
