'goon' -linguistic drift gave her a new meaning. i hope her new life is good for her. i miss her.

'henchman' -too gendered. can be shortened to 'hench' in a pinch, but lacks punch.

'servant' -too domestic to apply to all those who serve evil.

'underling, subordinate' -this one only works if they get off on being beneath you and/or you don't properly pay your workers.

'associate' -this one's good for grizzled mercenaries or lone agents but doesn't work good for broad swathes of an organization.

'slave' -same as underling but more intense. really fun for some of the group. unsavory for others in a way that limits the scope of the thing.

'thrall' -only really applies if you're brainwashing them and that's not something i've learned how to do en masse yet

'flunky, toady, stooge, lackey' -these are just insulting, and that isn't conducive to a healthy work environment. imagine going to work and your job title is 'stooge'.

'acolyte' -works for those that worship you, but again. lacks the scope.

'supporter, follower' -unspecific and vague

'assistant, helper, aide' -not sinister at all. just means you're doing things for me. swagless in this manner. could be good if used to describe someone who's so clearly more that as a way to emphasize their obedience via understatement, but that's only useful for a few members of the organization. and even then, 'associate' works better.
