Is revenge bad when?????????????/?

You have never did anything to people put they continued to pull you down when you tried to do something with your life.And then turn around and make it seem like your the crazy one and smile in your face and act concerned but plot on you behind your back.Trying to lead you into self destruction knowing you only have one life cause their lives are miserable and they want you the same way.People ain't sh!t man real talk and the messed up thing about it it be the closest one's to you.I think GOD should forgive you if you get revenge when you are constantly bein **** on by devilish people.When you haven't done anything to anyone.Plzzz all the down to earth people respond.
