In EA, the Paladins of Tyr that you find in the tollhouse and that ask you to kill Karlach were more nuanced characters who turned to Zariel out of desperation and originally actually were paladins (or at least Anders was), having turned from Tyr to Zariel out of despair over how he had been fighting for others while his own family died without Tyr's protection. He's nicer, accepts you refusing to kill Karlach if you've figured out the truth, and provides at least something of a quandary for the player. In the full version of the game, this backstory has been removed for seemingly no reason at all - except perhaps to make Karlach look better by comparison, but it hardly seems necessary and I find it hard to believe that it remaining in would've somehow caused people to kill a companion. The idea that the devils can be a more reliable or at least less demanding master, that the normal gods can be uncaring (foreshadowing Mystra's demands of Gale, perhaps) are left unexamined. Obviously it was not a great philosophical setup, but it was at least something, whereas the Anders crew in full release are just cartoon villains.
It's just one more example of how the 'darkness' and nuance of EA was scrapped in favor of Manichaean good/evil thematics, alongside more clear examples such as Wyll's rewrite. In any case, #JusticeForAnders
