If a scam involving high-up US[1] people (Kissinger was on the board) wants to involve you, here's a table for what will happen depending on your intended role:

Co-conspirator (everyone else organizing it): Nothing

Front person who talks directly with the higher-ups (Holmes): You'll get dragged through the media, but the high-ups won't let you get ruined lest everyone else see it and refuse to work with them next time they're looking for someone.

Axe-man who does the front person's dirty work (Balwani): You'll get thrown under the bus, because after working as the axe man for a few years, you've absorbed all the direct personal anger and discarding you means getting rid of part of the anger.

Peon (Theranos employees): You'll be hounded on the basis of your boss's guilty paranoia even if you want to comply and take home a paycheck, and when it all comes down you'll be out a few years of your life with nothing to show for it. Of course, this is no worse an end than what awaits employees at cultlike startups with bad management, except for the fact that you might unwittingly become a directly culpable axe-man bit by bit without noticing what you're becoming inseparable from.

[1] If the high-ups aren't enmeshed within the governing body you're beholden to, they can't protect you even if you're an equal co-conspirator or a front person they might need another one of in the future, and this ranking doesn't apply.
