He basically devalues EVERYTHING around him, all types of characters. Like someone above said, how do you make threats and villains after you do the ULTIMATE EVIL which is what the Sith Emperor is supposed to be. And he's shown to be able to actually do it... ...but just doesn't because he doesn't feel like he succeeds because he has basically a Force parasite that he's draining off of who is feeding him BS. Super dumb way to dumb down a super huge threat so you don't have to use that super huge threat. Imagine if in post-FOTJ story era they make a character that can destroy the galaxy. But decides NOT to because well.... what if the New Republic/GFFA (whatever the frak its called) *MIGHT* be able to stop it/him. Despite the fact that the Sith Emperor would never be at the front lines or anywhere near it, and that he'd be completely hidden on a remote and forgotten world so even if his Sith Empire attack didn't defeat the Republic and they'd have virtually no way to find his homebase.... especially with his ability to do complete mind control so he can brainwash his own troops not to remember his world incase of capture.... and the fact that he has complete mind-control but can't determine lying or motives of those in front of him (like Scourge and Revan).... yea.... stupid character... .stupid plotting.... stupid story .... stupid storytelling, stupid everything. It was like the TOR writers wanted 40K in Star Wars set pre-ANH but with everything that the PT and OT has combined. Dumb.
