Regulary, a imprisoned murderer for life cannot kill someone else, too.

Don't kid yourself. It happens all the time. You think convicted killers won't kill just because their new victim pool only consists of fellow inmates?

C'mon, let's get real here.

I said "regulary". And I don´t think that this possibility is sufficient to kill a one-time murderer. Also, my point taken, that deterrance doesn´t work any better with capital punishment than with life imprisonment is still unchallenged. You may have other reasons to support the death penalty, but deterrance is no reasonable argument.
I posted this because it was said "What a great message to future murderers" or so on this thread.
