Look, revenge is best served with a shit ton of karma soup.
Taking revenge and fixating on it to the point where it's your only goal will leave you unsatisfied and empty when it's over.
True catharsis is when you are able to show them exactly the same pain they showed you, nothing more and nothing less.
Though, even better is when you get revenge by being more successful in life then them and watching as they slowly fail as illustrated by Barbados who can't accomplish shit most of the time.
