An important factor is that this man could not have sex without endangering his company. There were billions of women he could cheat on his wife with, and about 1000 who would be dangerous to his company to cheat on his wife with. He continually cheated in that pool of 1000.

Otherwise I don't care if this old man has sex, I don't even like thinking about it. But he was reckless and up his own ass about it. And while I don't think that the chips are the gold they're made out to be, and completely don't buy the reasoning of how A. Huang's business would be in the service of Chinese "spying," she's certainly someone who could and would talk business with him. She may have been an advisor on the financial house of cards for all we know, and the Chinese would definitely be interested in destroying the US economy.

Hell, the covert Chinese action might have been to take a woman who is extremely suspicious, get her to sleep with Huang, publicly out the affair, and let the company fall into the hands of somebody who is going to do something very stupid with it. That would still be Huang's fault. Maybe, none of this has anything to do with the Chinese at all, and the Israelis financed A. Huang's company (which was also evading Chinese enforcement) in return for her seducing a known sexually incontinent J. Huang, they publicized it, and with J. Huang's ouster the firm will fall under Israeli control. That would also be Huang's fault.

None of this excessively involves lawbreaking or morality, just stupidity and incompetence. Which is not "business acumen."

It does seem instinctual; but plenty of people are able to override genetics with idealism.
