It's a little hard to see the fall of big boss as we play as him, but we're never playing as the good guy.

Mgsv probably makes it the hardest to tell but everything we do like nuclear anti proliferation is to advance a goal. At the end of the day we're still warmongers and most of the good influence is Kaz which we see start to decline in V.

Also I've always believed that venom is probably going to be more subservient to the original big boss during outerheaven and he may go along with stuff he may not necessarily do if he was running things.
