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.

Depends on whether they work in jail or not.

Re-calibrating inflation for the equivalent in today's money...

No work.
Net profit of DP = -$50000 for the law proceedings etc etc..
Net profit of 30 years in jail = at least -$200000, guards, overheads, food, a gym, cable tv(liberals force taxpayers to provide cable and gyms for child rapists)

Work.
Net profit of DP = -$50000
Net profit of 30 years in jail = $40000 (assuming they on average make a $8000 a year)
