So one would assume that it would be ok also to take ones life if they are defending their family, for instance, if a parent takes anothers life, because the aggressor is about to murder their child…then it is acceptable. Also, law enforcement personel may take anothers life in the line of duty…correct?
[quote=mtr01]Off the top of my head I would answer that it would have to be self-defense. A Catholic is permitted to defend his or her own life. If the attcker is killed as a result, then that death would fall under the category of an unitended “double effect”. In other words, protecting one’s own life is the motivation (or intended consequence). The death of the attacker would then be an unintended second consequence. A Catholic, however, is never permitted to take another life as a primary or intended action.
Note also that this is dependent upon a reasonable response to an attack. If one defends oneself from a slap by shooting the “attacker” with a gun, the above would be inapplicable.
I suppose, by extension, it could also apply to defending one’s country in a just war as well (inasmuch as you are providing defense against an unjust agressor nation).
