All this hand-wringing too on television dramas about "I must murder one person so as to save the lives of 100." Nope. You can NEVER do that. Then the 100 must die, and you leave it up to God. No moral anguish and cold Protestant calculus about whose life is worth more than another's.
Good point.
Notice that in such cases, the protagonist feels guilty about it, but he tries to salve his conscience by saying, "But at least I saved 100".
But the fact of the matter is, you'd feel no pangs of conscience if you DIDN'T kill that one man. Even if 100 people were murdered as a result, it's not like their blood is on your hands! The blood is on the bad guys' hands. It's simple, really. You had nothing to do with the murder of those 100 people, and you can't trust the bad guy when he says, "But -- pinky swear -- I wouldn't have killed them if you had killed that one man. So YOU PRACTICALLY KILLED THEM! Bwahahaha!"
No, it doesn't work that way. If you don't kill someone, your conscience is clean from murder.
Basically, murder is out of the question. People seem to have no problem considering murdering someone in cold blood to be out of the question for a Buddhist monk or a 70 year old bingo-playing grandmother -- why not everyone else? Murder should be off the table for *any* good person, let alone any Catholic.
