The Gods have been lying to you all along. You actually know fuck all about anything and will be put into stasis or outright executed the moment you stop being useful (collecting the souls of the dead for the war effort, including your old love interest who you can no longer remember because Odin broke your mind.) or when your mission is complete (defeating the totally chill Frost Giants who aren't the evil side at all). Turns out you're basically just a tool in the service of ruthless, despicable assholes. Your fight against evil has often led you to destroy the unfortunates who defied them.
Good thing there's a special ending where you finally get justice. ---
