Killing someone who is threatening to kill you is not wrong, because you're only doing to him what he is doing to you. However if the world is about to end and the only way to save it is to kill a one (particular) innocent person, I wouldn't do it.
How odd and strange! Those two sentences are completely contradictory! Are you sure that you don't want to rethink or restate what you're thinking?
However if the world is about to end and the only way to save it is to kill a one (particular) innocent person, I wouldn't do it.
What if that person were trying to kill your mother or your child? You'd just stand there and let it happen? ....without lifting a finger to save them?
I think you're talking in psycho-babble instead of using reality. I.e., you just want to talk in philosophical terms, devoid of any personal attachment to reality. It's easy to say things, but much more difficult to face things in the real world.
