This is the worst of the problem. Revan is offered up as a sacrifice to the greatness that is to be TOR's heroes. It's a fairly common sci-fi/comic trope -- and here it's very transparent. Use whatever the "great" thing is, and then own it by something even greater. It's just a shame that they've used Revan and the Exile to do it. It's not like it began with GAotS. We can simply go back to The Sith War -- the genocide of the Massassi by the combined Replublic/Jedi task force. Then, of course the genocide of the Sith Empire, led by Empress Teta forms the entire backdrop of the motivation of the TOR Sith Empire. Pretty much all of the ancient battles between the Jedi and the Sith in the '90s were about the Jedi trying to eradicate the Sith. Most would say not without good reason; but certainly, the extent -- genocide in a few notable cases -- might be considered too extreme. And it's certainly not something the Sith, themselves, have gotten over so easily.
