Whilst I was angry at the Borg for deceiving us all these years, I didn't remain angry, because I don't see any good from remaining bitter. It's a negative emotion, and for as long as you let yourself be bitter and extremely angry at the Borg, they still have a measure of power over you. I refuse to allow them to have that power over me.
My "revenge" against the Borg is to live as happy and meaningful life as I can now that I'm out. Life is to be lived, and I'm learning to embrace it in a new way.
After all, weren't we told that those who left Jah's org would be unhappy and bitter? Then what better advertisement for being an "apostate" than to be genuinely happy and moving on with your life? Prove their words wrong, and it will be a sweet "revenge" against them!
