Revenge is never worth it.

Never. No matter what ‘it’ is.

Well, if it costs you absolutely nothing… you might think. But here in this case you are talking about a case where it costs you a lot. So: don’t!

And even if you think that it costs you absolutely nothing, then it still costs you your nerve, a whole lot of extra negativity going round and round in your brain, etc. Better detach yourself from all of it.
