Life or death?

I believe that the death penalty is in fact morally wrong. In essence its really saying u kill and u get killed,but is this really right? Of course their crime comitted was harsh, immoral, and maybe without remorse, but does this make it right for man to determine their fate? If i were to answer these questions i would say no, a wrong and a wrong doesn't make a right. I also believe that life and death should lie in the hands of God and not that of man. However, there are other forms of punishment,such as life in prison, that could be just as effective without that level of cruelty involved.
