I have several reasons for opposing it. One is that being an irreversible punishment, it precludes any possibility of remediating injustices. There have been many cases where it seems highly likely or even proven that executed prisoners were innocent. The second is that particularly in the US it has become highly politicised. The possibility that condemned inmates might be found innocent, and the damage that does to the credibility of the system, has lead to the system doing whatever it can to obstruct and prevent investigations that might exonerate condemned prisoners, regardless of the strength of any evidence. So for me it's not so much that the punishment is bad, it's that it seems to be extremely hard to set up a process around it that is fair, and the US in particular has failed to do so.
