the eighth amendment

I think the 8th amendment definately needs to be more clear on what cruel or unusual punishment is in order for it to be a fair amendment. Because cruel and unusual punishment is going to be all opinion based, especially for someone involved in the crime, its difficult for anyone to really determine whether a punishment is allowed. I think the death penalty isnt the best way to teach someone who has killed another person, or is on death row, a lesson or show them how what they did has affected not only who they killed but also the people in the victim's life. Putting them to death isn't going to make them want to turn their life around and fix it because their life will just be ended.
