These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Saga of the Exiles
Magnificent Bastard - Marc Remillard, to a point. Sometimes he seems quite reasonable and gentlemanly and charismatic, but let's not forget he caused the deaths of four billion people, turned his son into a fish, and is STILL trying to find another world to take over to use for his Mental Man scheme- might I add that this involves creating a civilization of bodiless brains?
Aiken Drum is also a Magnificent Bastard, at least as far as the Tanu are concerned - he outplays them and the Firvulag at almost every turn. Marc beats him only because he's older and better at the game.
Woobie, Destroyer of Worlds - Felice; YMMV somewhat on how much of a woobie she is. But for a certainty, bad things happened to her and tipped her into raving insanity (and power).
