Revenge

Why do we hate people?  Sometimes, it's because they did something wrong to us, sometimes we just want it.
Personally, I believe revenge is right, I just don't know what the right way is.
My first view on revenge is to inflict a substantial amount of pain into the victim until you feel satisfied, I think this is a good idea.
My second view on revenge is this:
"The best revenge is to be unlike him who inflicted the pain."
I think this is also a good idea.
It is amazing how one day we love a person so much, then the moment they hurt you, all you want is revenge. A change of heart can happen in a moment's notice.
