It defies the meaning of friend if he didn't like that friend. Guilt isn't nearly enough to make a person crazy enough to forget your "daughter" so the witch gene definitely contributed there. Not to mention Echidna saying that she used to be human before, which implies that taking the witch gene removed some of her humanity. Then Subaru commenting that using the authority is taking something away from him (implied to be sanity again)

So the evidence points that the authority does affect the personality/behavior.
