There are times when there is no doubt someone did what they're accused of, but I'd hope that when there isn't zero doubt, the prosecution goes for life or life without parole instead. This ought to be tempered with the state levying murder charges against anyone who grooms a child to perjure themselves for the sake of having someone killed by the state on their behalf.

Death is too much to ask of an innocent person in their contract between themselves and the state. A guilty person, sure.
