Is it always the case that the end does not justify the means (morally)? Is there ever a lesser of two evils option?
I ask this because I was talking with a (Christian) person who believes killing is always, always wrong. I think Biblically that position makes no sense. But what does the Catholic have in place to determine what is and isn't okay?
I've hear a thing that the end does not justify the means unless you have no option but to allow the lesser of two evils. But then, going by that, in the case of an abortion when you're only options are to save the child or let the child die would you be obliged to kill the abortion doctor (something which is obviously wrong)?
I know you shouldn't kill the doctor (at least, I never would), but I'm just thinking about what system there is to determine what is right in different situations...
