Shanks villain theories really died
You are simplifying the conversation. It's not about Shanks being evil or bad. It never has been this way.
Btw, I never said he was any of these things or a snitch or some simple bad guy.
The movie does not answer this Question. It's obvious he's against the Marines and "some" WG goals. He's a pirate. The question is if he's at all against Luffy on any level (it could be as simple as competing with Luffy for one piece, thats it). The Gorosei conversation is still a very weird one.
