Karma is like a rubber band, you only stretch it so far before it comes back and smacks you in the face. What a funny way to describe it, I know, but then karma serves justice to victims and surely punishes the sinners, one at a time.

Revenge will never solve anything, karma will.

Just remember that all the shit someone puts you through, sooner or later karma will find its way to them.
 
No need for you to take revenge just sit back and watch, what it does and if you’re lucky, God will let you watch.
Remember, those that try to destroy your happiness, have jealousy towards you, they are unhappy with their own miserable lives.

The best revenge is always to just move on happily, sit back and let karma do the rest most importantly have patience too
