Durance doesn't hate women, he's obsessed with Magran.
Dudes like someone who married someone like Sasha Grey when she was still doing porn and gave everything for her, but couldn't get her to quit. He knows she's probably leading him on and doesn't care, that attitude was a big reason why he loves her, but he doesn't have proof. In the game he gets it and all his suspensions fall into place.
As for foreigners, he doesn't hate them he hates the Aedyran for their empire and what it did to his people and the Readceran for being poor, weak farmers, not strong and industrial like his lot were, especially for also worshiping meek Eothas and not strong Magran. That point is made all the worse by the later revelation behind the Saint's War and realizing that he ultimately was on the wrong side.
If he's anything he pretty much something like a modern atheist or someone hung up on old European paganism that hates Christianity, works to rid the world of it only to realize it was not only right but the good it was doing for the world and that his beloved cause was for nothing.
the Exile is just a mean to an end
Like hell they are. Kreia is obsessed with the Exile because they can live without the Force, the big thing she's wanted in her life. It's why she despises Sion despite the power he had, it all came from the Force, so
he wasn't the source of his strength and was nothing in her eyes. She lived vicariously through the Exile, loving influencing them and hoping they'd see her way in that creepy was trainers and others latch onto athletes and conflate their achievements with their own.
Durance resolves nothing,
Here's a hint about PoE's thematic foundation: NOTHING GETS RESOLVED!
The theme of the game is about the futility and meaningless of life and every quest revolves around that to some degree or another, especially the companion quests. Picking that theme to build a
game is not a good idea, it is not fun and will produce apathy in ones audience unless the entire thing flies over their head.
Even when it comes to companion quests that might be able to be resolved some what, like Aloth's, they still end with big shoulder shrug and sigh, not even an attempt to try to resolve the problem it anymore.
At least in the case of Durance his past actions get put into a new perspective that destroys his old world view and shows exactly how evil he is: Eothas was right. Not only that, Eothas was the only real god who did care about mortals and practiced what he preached by coming down and trying to stop Waidwen's Legacy before it began. All that rhetoric Eothasians prattle on about was completely true and puts others actions into perspective as well: Eder part in the Saint's War was also on the wrong side, his brother's actions joining Waidwen were proven true, but we don't get to see that in his own side quest, we just come to a ruined, buried banner where his brothers trail runs cold and the last conversation about is Eder admitting he'll probably never know the truth.
If you want to make a movie about something like that, it can work. A book? Can work. Pretty much any other form of art and it will, but you cannot make a game that is futile and goalless because it defeats the entire purpose of what games are. It's also why PoE is constantly limp and drama-less: The story has no resolution, no real goal, and yet the very mechanics of a game require them so we go from plot point to plot point, place to place doing things that carry no weigh and make no attempt to invest us.
The main difference, and an important one at that, is that while Kreia sucessfully manipulated the Exile to some degree, Durance was a total washout.
None the of the game mechanics nor dialogue really allowed for him to while KOTORII was really built around it even if every answer you gave her was wrong and provoked a rant from her.
