Justice

You shan't kill others.

This seems iron axiom, but actually it's not, instead we have to say that You shan't kill others unless they do harm us.

When we found venom in our society, what shall we do? We keep on enduring without doing anything? No, it's not the kind of answer. We have to expel him out of the society we belong. It seems to me we need another venom to remove him. Actually we don't call the way to expel him venom, it's justice instead.

Justice should be done not only from someone's decision, but collectively. Otherwise we all are likely to be victimised from him. That ought not to be done. Oftentimes we our society as a whole collectively decides to execute someone. If someone did harm to us, we call it justice not manslaughter.
