I'd quibble with the framing, here: Dudes like SBF don't really have friends in the way most of us use the term. What they have are _associates_ - who are really often just slightly more-favored marks. Remember that SBF is a dude who deeply internalized a #MasterMorality version of Utilitarianism that gave him carte blanche to ignore conventional ethics, so things like 'friendship' are gonna be highly relative to him.
