At some point, artificially extended life spans may become feasible and common.

It seems to me if/when that happens, a life sentence should be considered cruel and unusual.

Depends. Do immortals become more good / lawful, less good / lawful, or does it vary?

What are you going to do about the incorrigably unlawful / evil?

That's a hard line to draw, when including things like drug overdoses, hunger strikes or suicide.
