Capital Punishment...Why Not?

First off, I'm against capital punishment. This 76 year old prisoner was "blind and mostly deaf, suffered from diabetes and had a nearly fatal heart attack in September only to be revived and returned to death row, [and] was assisted into the death chamber by four large correctional officers and lifted out of his wheelchair." His lawyer appealed his execution saying that it was cruel and unusual punishment to kill a man at the prisoner's age. Again, I am against capital punishment. However, I would be begging for them to kill me if I was 76, blind, mostly deaf, diabetic and in a wheelchair on death row! I think the state did him a favor.
