I grew up under a bona fide dictatorship. The dictator had three kids.

The youngest brother turned a power-drunk jackass, like Saddam's kids basically. Was given a job leading some part of the country, no doubt being groomed for the top position eventually. That didn't work out, he got caught during the revolution, and was thrown in jail for his abuses. He died in prison from some liver disease due to his prior heavy drinking.

His older sister tried to have a scientific career, studied math and actually worked as a researcher for a while. Her parents were unhappy with her career choice, so she got pushed into a "leadership" job - but within a scientific institute. After the revolution, when her parents were arrested and executed, she couldn't adjust to the new situation. I'm guessing she was probably battling a host of issues such as anxiety and depression, and quite understandably after the violent end of her parents. Started drinking pretty heavily and died from lung cancer a few years later.

The oldest brother became a physicist and, by all accounts, was the only "normal" member of the family. Of course he got arrested during the revo, but was freed soon afterwards. He's the only surviving member of the family, and AFAIK he's still working as a scientist today. I've studied physics at a college near the institute where he's working; it was common knowledge there that he was basically a normal person who got the job on his own merits.
