Do video games count? If not, ignore this.
Teryn Loghain Mac Tir of Dragon Age: Origins. IMHO, (and this is a BIG IMHO, as I know MANY people despise him) there wasn’t a thing he did in Dragon Age: Origins that wasn’t entirely justified. Even his worst action, turning a blind eye to the Tevinter slavers in the Denerim Alienage can be understood even if it’s probably going too far.
If you recruit Loghain into your companions and press him on it: He’ll defend it by saying that he calculated that when the Darkspawn attack Denerim, the alienage will be almost impossible to defend and that the Elves WILL be massacred. With the funds from the Elven slaves, he can improve the defences of Denerim, ensuring that only a few Elves are sacrificed to keep many alive.
And then there’s the “betrayal” of King Cailan. King Cailan betrayed himself and the soldiers under his command by going into an unwinnable battle despite his best general with every fiber of his being telling him it would end VERY BADLY.
Is it any shock Loghain retreated from the field instead of getting yet more children orphaned and more wives widowed for some golden-armoured, pompous idiot’s ego? (Also, if Loghain planned to betray Cailan before Ostagar, he wouldn’t have advised Cailan to engage the Darkspawn more sensibly. In fact, he would’ve encouraged him to do so. I very much believe Loghain had no intentions of “betraying” Cailan…until Cailan insisted on and defeating the Blight in one big, “glorious” battle that the bards will sing of for centuries. No doubt emphasising how “virtuous” and “heroic” King Cailan was.)
And then let’s not forget the Return to Ostagar DLC, where you find out King Cailan and Arl Eamon were planning to divorce Anora (She hadn’t been siring any heirs to the throne, so naturally, Cailan decided Anora was at fault and must be barren.) and marry the Orlesian Empress, of all people.
(Bear in mind, Dragon Age society is very equal when it comes to gender. When Cailan and the Empress die, the thrones would pass to their eldest child. Naturally, with the Empress being the dominant and higher ranking partner, the child would almost certainly be raised in Orlais and his primary title would be "Emperor/Empress of Orlais. Fereldan would become apart of the Orlesian Empire again, the very thing Cailan’s father, Arl Eamon, Loghain, Teryn Bryce Cousland, even Arl damned Rendon Howe fought against.)
He also, lest we not forget, was Fereldan’s greatest hero at one point…And IMO, still is. Far more heroic than Cailan could’ve ever been.
