For everyone's consideration, the Renegade KaidanRobCoxxy said:He has an interesting backstory. And he's not a total racist ***** like that whore of a squadmate, Ashley.
When it came to that section in Mass Effect 1, yes, it was tense and emotional, but I did, essentially, just go "BYE ASHLEY."
Yes, he can be actually. Clearly he was just persuaded into the dark side by a renegade and how here he is calling out some pretty severe racial hate and pro human extremism. Now I actually think this is kind of sad because he had the right mindset about aliens but he was so easily swayed into the wrong path, by someone manipulating his past traumas to make him into a true monster.
Also while we are on the subject:
Yes, that is Ashley moving on past her pat prejudices towards aliens and moving on to trusting aliens and the Council in general. Not how she also makes clear that she doesn't think humanity is 'superior'. It's also made clear that her distrust of aliens is based on bad family history and not a personal irrational fear and hatred of the unknown.
So there you have it, a reformed racist Kaidan and a reformed alien loving Ashley. They are both opposites of each other that can be influenced either way at the behest of the player.
