No, Shisui loved Itachi as a brother and the best friend he ever had. DB4 confirms they were raised together/grew up together. He was closer to Itachi than he was to Sasuke and he knew the truth behind Itachi's actions. There's a high chance he could hate Sasuke for pushing Itachi into killing himself. As Orochimaru said quite clearly, some people change and it's not always for the best.

Not good quality but look at Shisui's left eye. http://i295.photobucket.com/albums/mm155/BenderSSJ/TobiDanzo.png~original
