But that's not because I myself am evil - but because THEY are!!

Two questions, Eli.  Isn't revenge both natural but inherently evil in itself?  Secondly, do 2 wrongs make a right?

There was an interesting discussion on Nicky Campbell's 'Your Call' last week where this was the underlying topic.  Does a harbouring of feelings of revenge (also referred on the programme as a refusal to forgive - albeit not forget) actually do damage to the harbourer?  Is there not a danger that it acts as a canker inside slowly poisoning all aspects of one's life?
