Personally I don't even think there should be a punishment system, but I accpet some people need to be removed from society sometimes. If some one is a danger to society they should be removed and rehabilitated. If they cannot be rehabilitated then they must stay separated from the rest of society. Punishment serves no purpose but retribution, and imo retribution is not a worthy cause, it doesnt serve any purpose other than making some people feel better, some times. Capitol punishment is the ultimate in punishment, but it does punish innocent people, like the children of a murderer who could lose a father, or a wrongly convicted murderer.
