True, I get the feeling he repressed the idea of questioning Itachi's motives out of fear that he would discover something and it would make him unable to go through with killing him after all hating someone is a lot easier than trying to understand them. In the fight with Kabuto, the Uchiha brothers still display a remarkably strong bond.
