Many people are familiar with this quote by the 16th-century English metaphysical poet, George Herbert: "Living well is the best revenge."
Fewer indeed know the context in which that "revenge" is situated -- "He that cannot forgive others, breaks the bridge over which he himself must pass if he would ever reach Heaven, for everyone has need to be forgiven."
Go ahead with yer Bad Self -- get your revenge. Forgive and live well.
