Some good and some bad ideas floating through here.

It's a long-standing debate as to what the purpose of our legal system is. Should it seek justice, or should it seek to rehabilitate people so they can one day contribute to society again?

I am personally against the death penalty, but I do think whether or not you embrace it goes to whether or not you think the judicial system needs to seek justice, and then what exactly justice means. If you do think it's about justice, then what is the just response to murder? And if it's not about justice, then there is simply no leg to stand on for capital punishment.

Personally, I think it's not a good idea to try to convince people not to kill people by killing people ourselves. Idiotic, really.
