Why wouldn't it make sense? As I recall, Sasuke stopped hating Itachi upon learning Madara's version of the history and truth. Not to mention he would probably want to slay Oro's remnant anyway. What comes to B, it would be more than fair considering Kabuto is the one who resurrected Itachi. It would be the ultimate justice the jutsu he has been spamming left and right (after robbing graves left and right) comes back to bite his own ass. Sasuke would be just an additional bonus. I doubt he would like somebody to mess with his brother's soul and body anyway, considering most of his life has been about revenge.
