Would you be for a world ruled by Doctor Doom? A world with no disease, hunger, or crime. A world without any freedoms where Doom's word is law and breaking any law results in immediate termination. Would a utopia for all be worth giving up your freedoms?
Freedom? Freedom is relative and not absolute by any means. We are capable of anything we want but will often hold back because of unwanted consequences.
A world where offenders are summarily dealt with would merely be speedy execution of what merely takes longer in our world. You do bad you will pay sooner or later, on that world the waiting time would be a lot less.
@lorbo: Wow, I never said that Bad Guys shouldn't be punished because they should. I was just saying a dictatorship is not the answer. Justice is. Freedom is the right of all sentient Creatures. But its a Freedom to do what is right, and not a freedom to do whatever you want(because even in a dictatorship people still do what they want).
