If It was a baby or something I would have to say no but if its any older then 18 go for it lol Wait... Can we sacrifice Nancy Grace? thats for the greater good
Why is it better to kill something that has nothing to lose, to somebody that will be missed and probably doesn't want to die.
For me it depends on what you mean the greater good is. If you're talking about sacrificing a life someone to save my family and/or friends (i.e. murderer) I wouldn't think twice, but for their greater good (i.e. putting them out of pain) I'm not sure what I'd do.
