> This wasn't justice. It was revenge. There's a difference. Justice accomplishes something. It keeps a bad person from doing bad things. Revenge only makes things worse.
I disagree with your definitions. I would say justice is sanctioned legally, while revenge isn't. Aside from that, they're nearly indistinguishable. And given what is and isn't legally sanctioned by countries ("torture" for example), I think the difference is even less.
