Don't judge a book by its cover

While he was absorbed in his thoughts the door was pushed open as a eunuch announced the arrival of Emperor Rui's subordinate. The subordinate kowtowed before him but before he could pass on his formal greetings to the emperor, Emperor Rui stopped him and told him to skip to the report.

The subordinate lifted his head slightly afraid even to make a sound. This man was incredibly ruthless. In front of his father, Emperor Yu, he slaughtered each of his siblings one by one with his own hands.

And when the former emperor tried to kill himself Emperor Rui forbade him restraining him on a cangue and making him watch on under heavy guard. He had gotten rid of everyone who used to serve Emperor Yu replacing them with his own people. This meant no one would take pity on him and pass on poison to kill himself.
