After i read the chapter I think that man is related to itachi and shisui,maybe his supporter/subordinate or a close friend.He become hate sasuke because,sasuke kill itachi and the sacrifice of the people i mention above would become vain worthless.Because of that he do all process in order to avenge the two and their sacrifices and i think the product of that is the birth of the "fake uchiha".
