Is that a real answer...do we have a button pusher?
Some people say that it is mean and that they wouldn't want to do that to anyone...what if you are doing it as a favour. It could be a cancer patient that is fighting a painfull loosing battle. Or a 90 year old stroke victim that is liveing in there son/daughter's basment, and causing a finantial burden to his kids. Or a wife beater...or a terrorist...
what if you didn't push the button, and as a result, knowone died...but the person that would have died is still alive, and ends up being responsible for multiple murders, including one of your close loved ones?
