I get it. I know this is probably what people wanted, him just murdering people in cold blood, but I just don't see Disney signing off on that.
It kind of seems that he chilled out once he had his armor back, aside from killing Fortuna. Maybe because he didn't want to end up like his father...dead? He's the only one who didn't storm Gideon's cruiser, so maybe that was the start of the change in his priorities?
Like I said in another post, I'm just trying to find ways not to hate it, because I don't want to hate everything Star Wars. I send enough vitriol towards the sequels to last a lifetime.
