The
Jedi Council was the governing body of the Jedi Order, consisting of 12 masters. The entire council were dicks (except for
Obi-Wan, Yoda, Plo, and later Anakin). Mace Windu was the biggest
asshole of them all, not even apologizing to Ahsoka and later calling her a citizen. He was also unsympathetic towards Boba Fett, whom he'd practically orphaned. The rest of the Jedi Masters just followed his example, and led the entire Order to be hated galaxy-wide, viewed as being no better than the
Sith.
Put simply, the Jedi Council were (mostly) assholes.
