I think Scott was tired of being a scapegoat when others had problems, too. Like all the VR guys except Kushner relapsing, but only his being news or a problem. That said, being the singer is like being the President or a famous coach--you get all the credit, but the flip side is you also get all the blame. It isn't fair, but he knew that.
That was a convenient way for Scott to deflect and not take responsibility for his actions as well. The fact is that the members all realized on their own what had happened and straightened themselves out. Scott wasn't until tour dates were cancelled. He was becoming a millstone, threatening to drag them all down, especially in terms of how much these cancellations cost. Any reasonable person would even be able to look past the finger-pointing "what about you?" stage and eventually say "you're right, I really need help." I mean, Steven Tyler got to this point eventually, even if he never fully GOT the meaning behind the interventions on him, or what he was asking for in asking Joe Perry to go into rehab at the same time and miss the birth of his child in 1986.
No, Scott was content to simply rant, rave and shut himself off, and insist that Dean, Robert, Eric, Slash, Duff and Matt had to get on their hands and knees and beg his forgiveness and say they'd been hypocrites. All the while he turn a deaf ear to any kind of helpful advice. Take all the battles over publishing and earnings throughout the making of Libertad, and how it was solved by lawyers and management saying they'd take a cut to give Scott more money, and Duff says "in retrospect, they should've held their ground and refused to cave to Scott." It again shows how Scott burned his bridges and only wanted them rebuilt on his own terms, terms that had no basis in reality.
