I’m not sure. Protecting my family would be important but the attackers life isn’t mine to take. I’m not sure what I should do in such a situation, which is partly why I started this thread.
I’m amazed that you say that. You don’t know if you would simply stand by and let your family be killed.
I’m sure you are aware that God gave the Church authority in matters of faith and morals so all Church teachings are fully supported by God.
The Church teaches that not only are you allowed to defend yourself, family and country even if it means using deadly force, but it is your duty to do so. Self defence and defending your family and country is NOT an evil act. If you think it is then you are contradicting Church doctrine.
CCC 2263 The legitimate defense of persons and societies is not an exception to the prohibition against the murder of the innocent that constitutes intentional killing. “The act of self-defense can have a double effect: the preservation of one’s own life; and the killing of the aggressor. . . . The one is intended, the other is not.”
CCC 2264 Love toward oneself remains a fundamental principle of morality. Therefore it is legitimate to insist on respect for one’s own right to life. Someone who defends his life is not guilty of murder even if he is forced to deal his aggressor a lethal blow:
If a man in self-defense uses more than necessary violence, it will be unlawful: whereas if he repels force with moderation, his defense will be lawful. . . . Nor is it necessary for salvation that a man omit the act of moderate self-defense to avoid killing the other man, since one is bound to take more care of one’s own life than of another’s.
CCC 2265 Legitimate defense can be not only a right but a grave duty for one who is responsible for the lives of others. The defense of the common good requires that an unjust aggressor be rendered unable to cause harm. For this reason, those who legitimately hold authority also have the right to use arms to repel aggressors against the civil community entrusted to their responsibility.
