meh. i was just stating my opinion. i believe that if you continue bloodshed, it simply wont stop. you kill someone, so you're given the death sentence... why not stop the killing and just keep the person away from society? i admit i was probably going overly dramatic when i talked about solitary, but the people who first criticized life imprisonment were talking about the need for a harsher sentence. they said that it would comfort the family that that kind of person could never get out of jail again. i was talking about a specific circumstance, in which a rapist/murderer/pedophile was involved, so if you're going with the "eye for an eye" punishment, as i believe vasu was just advocating, you WOULD be going with that, locking up a person with no way out, just as the criminal had given the child no way out of it's hell. im not advocating that kind of thinking, neccesarilly, but simply pointing out a flaw in your argument.
But also, the life sentence, as stated previously, would give the innocent a chance at getting back out. you cant really go and ressurect a guy who just got the lethal injection, saying "oops... DNA evidence just came out. sorry about that

", though it would still be quite horrible for a person who spent like, 10 years in jail to get that news too...
