Darth Vectivus: A Pragmatic Contemporary Sith?
After reading his Wiki page, Vectivus has appealed to me greatly due to his ability to exist as a benevolent sith, if you will.
It was his strong pre-existing self-discipline and business mind/reasoning abilities that allowed him to resist the corrupting aspects of the Dark Side while still being able to wield its power.
I suppose you could lop him, Darth Gravid, and Kel'eth Ur in the same boat as light-sith, benevolent sith, whatever you wanna call them.
To me, it seems that the sith that have always caused the greatest havoc were those who never had any self-discipline or reasoning abilities (e.g Vader, Malgus, Caedus)
Vectivus never had any conflicts with the jedi because he simply didn't need to. They were of no threat to him and his personal lust of power didn't result in galaxy-wide suffering to where the jedi needed to hunt him down.
If other Sith adhered to the principles of Vectivus, I believe both the jedi and sith order would've been able to co-exist peacefully.
Also, contemporary businessmen like Elon Musk are mirrors of Vectivus if you ask me.
