The point of the first two movies is that Ben is a selfish, violent prick pro-actively making the choice to be a monster so the half assed redemption arc JJ gave him isn't really praiseworthy.
It's a bad script but it's not a cowardly, self-flagellating corporately mandated nightmare jumping constantly between the worst kind of fan service and begging for forgiveness from an audience that was always going to reject it. I hate Colin Trevorrow more than almost any other director so the fact his version would have been preferable is astoundingly. For the record, I don't really blame JJ for how that movie turned out - there's no way that was the movie anyone wanted to make.
