About revenge....
I am strongly Scorpio. I have Sun and Mercury in Scorpio, with Mercury conjunct the descendant.
I have Moon conjunct Mars/chiron in the 8th house
I have a tight T-square to Pluto conjunct BlackMoonLillith conjunct the South Node.
So the Scorpionic vibe is pretty strong.
But I have never been one to plot revenge against others.
Now, in my younger days, when battling other women for the men of my dreams, I could be manipulative and secretive and did set a few schemes in motion to try and show some of my adversaries in a bad light...
I think one of my biggest weaknesses and worst traits, in my younger wild years, was lust, and the weakness that could come over me if I wanted physical affection/attention.
At the time, it didn't matter if the other person was single, or a good person for a relationship. I would ignore all of that and pursue a fling. THEN I would find myself in complicated and difficult situations that could have been avoided...
Maybe my Venus in Sag in the 7th, ruler of my Taurus rising, was to blame...
