Statistics don't matter, even if one innocent person is saved it's worth it. There is absolutely no advantage to the death penalty. I'm sure if you told any death row survivor (eg: Damien Echols) that you don't think it's worth abolishing it because their lives were over anyway they would have a strong disagreement. An important consideration is the way death row inmates are treated too, 10 years on death row is not good for a person so if they are found innocent they will have suffered serious damage (Damien Echols again), it's a complete waste. Damien Echols did an AMA on reddit last year: http://www.reddit.com/r/IAmA/comments/107jib/iam_damien_echo...
