Arguing that fission power won't do anything is objectively incorrect.
That's an opinion, regardless of whether it's true or not. The analogy is analogous because I'm taking the same actions and statements, applying them to analogous topics in a different field. Dismissing that because you believe your beliefs to be objective fact is just dishonest.
I haven't gone through it myself, but I think Baldur's Gate 3 has ways to side with "bad guys", I believe I've seen patch notes about expanding the content there, so that's also an option from the same devs.
But the origin characters generally aren't perfect and have their motivations, especially The Dark Urge.
