There's a logical argument for the death penalty?
Yes. No murderer who has ever been put to death has subsequently reoffended. This means that society is then 100% safe from that person.
But you can't protect them from those that haven't murdered yet. You can't protect society from murder, just one particular murderer. One can also imagine (admittedly fanciful) scenarios in which a condemned murderer puts out a hit on someone, to be carried out if and only if he is executed. Isn't it murder to order a murder?
You can, though, protect the innocent from wrongful execution by ceasing executions.

The only way to guarantee that society is 100% safe from a serious murderer is to execute the murderer. Otherwise you're just hoping that the person won't kill again inside or outside of prison.
It's also fair to note that murderers who are sentenced to life pose a threat to other inmates. Can't it then be argued that the other inmates deserve to be safe from such killers?
Solitary confinement. Supermax security. Sure, you can't protect everyone from everyone else, but if you're doing your best to protect the lives of some from the one without infringing on the right to life of the one then at least you can claim that moral ground.
