The bad: Hizdahr comes from a wealthy slaving family, thriving financially in the human market. He frequently questions Daenerys publicly and makes her look like an incompetent ruler, and he's far too invested in the gladiator-style Mereenese Fighting Pits, where countless slaves have lost their lives for the merchant class's enjoyment.
The good: For all of his faults, Hizdahr does help Daenerys learn a lot about ruling. He teaches her balance and how to engage with the upper class in cultures she's unfamiliar with. Plus, despite suspicions that Hizdahr might be involved with the Sons of the Harpy, he is proven innocent when he saves Daenerys's life — and loses his own — during a deadly attack.
