Any death penalty will create wrongful executions. It simply can never be perfect. How many innocent people is it acceptable to execute as long as we also execute guilty people?

To me that is none.

Any death penalty also means that there is an incredibly high level of trust in the government to be accurate and thorough and not corrupt. In the US thats the same government that allows the Epstein class to walk free right now. You trust them to wield death penalty?
