You'll probably find this to be a volatile issue before this poll & thread run their course-- one of about 5 on this site. And there's a couple of those that I will not comment on any longer. Normally, of course, it is wrong to lie. But my position on this corresponds to other moral questions. There is a recent thread about 'modesty in medical sitautions.' Most agree that normal rules of covering our bodies do afford an exception for medical reasons. And I have used an illustration from an old TV western (Wagon Train, I think) where a teenage boy was captured by Indians and when a search party found him he was in a clearing, tied to a stake with brush around him. One man ran toward him but was immediately shot by an arrow. Then a flaming arrow came and set the brush on fire. So the boy pled with the other man to shoot him rather than let him burn to death. And the man did, as I think I would have, too. And if I had been that boy, I know I would have made the same request. Would you shoot him in the heart for a quick death, or obey "you shall not kill" as he's dying a slow torturous death anyway?
So, I do say there can be situations that change the normal rules. I don't, however, think that lying 'to keep from hurting someone's feelings' warrants such a change, as many, probably most, people seem to think. It's really a matter of how dire the situation. But face it, we are taught lying and hypocrisy from early childhood... e.g., "When you go to your friend, Jimmy's, tonight, eat what's on your plate and tell his mother it was a good meal, no matter what you really think." It can be hard to uncondition that.
