you should only be sorry for being so dumb. You understand the point of a JUSTICE system is to right wrongs so that those who crimes were committed against don't do it themselves. what kind of justice is keeping someone who took another persons life, in cold blood, alive? It's not even defensible. If that was my wife/gf/daughter/mother etc, i would want the guy DEAD. And in this case I'm glad he suffered. If she was someone close to you, what would you want his punishment to be?Yes, using barbarism to counter barbarism is barbaric. Sorry if my ethics are higher than yours.
Prison isn't for rehab, it's punishment for committing crimes against others. You can't make up the debt to society when you kill an innocent woman, you can't bring her back, so you deserve the same fate. That's 'fair'.
