I've noticed that many entrepreneurs have this immense drive and very little ethical/moral sense, and this helps them get by the most dire situations, where common people would simply give up, because they simply go on with a "fake it until you make it" mindset. Entering very dark grey areas and leaving a lot of bodies behind (figuratively speaking).

There are the stupid ones of course that don't get far, but the smart ones are the ones who really shine, I have a acquaintance who owns a unicorn and he is exactly like that. I'd never work for him.

I think it must pretty similar to the corporate psychopath profile who many times gets into the CEO position in big companies.
