It's been ages but if my memory isn't lying to me...
Hidden in case anyone hasn't seen or is going to rewatch
you're right about the bad guy end up being a VP, the whole story unravels in front of Robocop and the company's board, and the dude is standing there smugly because one of Robocop's core directives is he can't kill an executive of the company. The CEO in standard 80s action movie style says "hey ... you're fired", Robocop pauses long enough for the bad guy to realise what just happened, then shoots the guy
Also the above is for the first movie, I think the second movie is where the sentry thing does the deed.
I should dust these off and watch them again lol
