The biggest one is that I have absolutely ZERO faith in the integrity of the U.S. justice system -- including judges, jurors, and especially (in light of what we've seen in Washington over the last 18 months) law enforcement officers and prosecutors. I'll accept an imperfect criminal justice process as an inevitable flaw of the human condition, but the finality of a death sentence has always been a real problem for me.
The justice system is administered by humans. There is no other choice. Humans can make mistakes sometimes intentionally. I unlike you have faith in the justice system and certainly zero is hyperbole.
In the last 20 years with DNA, groups who do independent investigations of capital punishment case, liberal courts, and other technological improvements, executing an innocent person is very unlikely and becoming more so.
The question is what is the benefit to the death penalty if it is moral and we do our best job we will have some one innocent executed now and then.
What should be the penalty for someone doing life after a murder conviction who kills a guard or other inmate. Then can we execute them? Why can a police officer shoot a person who draws a weapon beefier they fire it. Shouldn’t they wait until there is a shot to make sure the person is intending to kill them? We give that power to the police because not is moral for the officer to live and the person drawing a weapon to die no matter what they are thinking or intending.
Do we not attack city in war knowing innocent civilians will die. Why because the benefit outweighs the negative. Life is too important to let people kill others and then maintain their own freedom of life.

Your zero faith in the justice system is completely irrelevant vis-vis the practicality of the death penalty itself!
living 30 years longer than the victims is hardly finality.
