Actually, it is exactly what they deserve: Death. Reasonably instant and reasonably painless.

This is the maximum penalty allowed by the Law and Constitution in US. Anything more and you're getting into territory forbidden by the Eight Amendment for very good reasons.

I apologize for my lack of clarity. They do indeed deserve death, but the death they deserve is not a reasonably painless one, considering what they did to victims.
