The Death Penalty

I'm a moderately pro-life libertarian.  I don't really know much about the death penalty yet, and haven't formulated a position on it yet.  My initial inclination is to be against it, but I'm not sure yet.  If anyone has some strong views on this from a libertarian perspective, and would like to influence me, speak up, now is the time.

"and frankley, i think the idea of living in isolation for the rest of your life with no possibility of release a better punishment than an alcohol swabbed arm and needle to the vain."

The goal isn't to punish them, it is to remove them from society so they can't harm more people, and maybe to rehabilitate them.
