An eye for an eye is a beautiful thing.
I'm gonna have to disagree with that. When it comes to laws, it would be better if we tried to fix problems by helping people out instead of doing the same things to them and hoping they understand. Some of the people who commit especially bad crimes view things much differently than others would and won't understand if we don't try to help them out. That is to say that nothing will be accomplished.
Having the best law system that creates the best society means that, imo, we have to stop our emotions from making decisions. People can still hate each other and want each other to die, but it shouldn't be the law. Something that is unconditional, binding, and the government must do to you. I'm not saying it would be okay for the people to physically harm others as punishment, just that the government shouldn't be killing people like that.
Eventually we're going to have to drop the idea that some people legally deserve it. Because regardless of whether or not they "deserve it", it isn't actually gonna fix the problem, but instead just make everyone else feel like they've done something good when they haven't.
I have really weird views on jail that I've been holding in for a while. I can say right now that they won't be popular ones, lol. However, I think in the future, when we look back and see how we solved problems in 2012 with government-issued violence and locking people in cages to "fix" them, we'll have to wonder why we were being so silly.
