Waters was silly and painfully naive in assuming when he had made up his up to leave Pink Floyd that the other three wouldnt have the inclination to continue without him. Obviously his ego had become inflated to the point that in his mind he was Pink Floyd. So it came a huge shock to him that it wasnt all going finish tidily with good timing and no loose ends, when in fact he had been outmanouvered into giving the others exactly what they wanted! i.e. him out! and them carrying on to a promising future without having to suffocate under the Waters total domination as the only one who had total control and absoloutely the last word in all matters concerning the band. Understandably he felt beside himself with rage not to mention total humilation to have been played so easily for a fool to find himself standing on the outside looking in! I think its taken rather a long time for him to come to terms and accept it. So at the time your probably right when he gazed into a mirror he would have seen an Areshole gazing back.
