He burned alive 40 students and 2 teachers for objecting to having the Roman Eagle God placed at the entrance of the Temple.
He had a group of dignitaries rounded up with orders to have them killed after his death so there would be morning.
All in all not a pleasant guy to have around.
He didn't do it alone, either. Those minions in power that were HIS favorites kept him in power. LOTS of baksheeh handed out, I assume.
