If they had given Stanley Poole a hotter picture the shipping wars on who to pair with Delta would have been both apocalyptic and texturally interesting.
Who is worse: the man who sets up the system that incentivizes evil deeds, or the man who directly does the evil deeds?
Sinclair never directly laid a hand on anyone but his actions led to orders of magnitude more suffering. He never chose his victims though, they were either handed to him or “chose” to engage in his schemes. If the contract says you’re going to have a bad time, Sinclair has no problem enforcing it even when face to face with a victim (like when he evicted the wife of a man he knew he’d got locked up in prison and her innocent little boy).
When faced with the chance to leave Delta to die he actively rejects it and chooses to do good, even when it kills him. When it comes to looking a man in the eye and betraying him, Sinclair won’t do it. Their contract was going together, and he stuck to that.
Poole directly killed everyone in Dionysus Park and personally handed over Eleanor and Delta to the systems Sinclair set up. He was entrusted with Lamb’s money and people and he had no problem betraying that personal trust. He like Topside as a person and fed him to the wolves. His actions led to fewer deaths than Sinclair’s, but they were personal direct betrayals.
Both of them absolutely harmed Delta and Eleanor. There is no innocent man in Bioshock 2 to ship Delta with. Shippers WILL have their due.
The purity arguments over which ship is morally correct would have been so toxic it could have derailed any more production of anything set in the Bioshock universe forever.
TL:DR Twinkified Stanley could have stopped Bioshock Infinite
