Revenge is for stupid people who lack positive direction. Do something good with your life and you won't have time for such petty things.
Revenge will trap your soul in bitterness, moving on is your rebirth.
Revenge is chains, a positive sense of direction and mission is your liberation.
You can come up with all the justifications you want for revenge, yet it will always be the work an inner tantrum and thus can never represent your best or what you could have been capable of.
Love and hate are from the same part of the brain, and so those who never developed a healthy capacity for letting go, can become the prisoners of revenge.
Are you setting the scene for a good future or cold retribution, for one builds your capacity for love and creativity, for real intelligence, the other is a pathway to emotional indifference, ever the sever swap of evil deeds. Revenge is an ugly thing.
In my experience, it is the most hateful who have cause the most harm to others that are the ones who want revenge. It is a close cycle of emotional immaturity and underdeveloped emotional intelligence. It is the logic that if they feel pain there must be a person whom deserves punishment for it. It is childish.
Revenge is not a dish to serve cold, it's a knife with rusty edges kept by one with blood on their hands. It is a disfigurement of shame that has been hidden from the self.
