So I think the decision to become a rat was right, not only to protect himself, but because that is not the Cosa Nostra he once swore to.
I agree with a lot of what you say here, except for this point. If the society is above the individual (which is what it's supposed to be) then if he were a true believer, he would not have become a rat to save himself just because Gotti was a public figure. Look at Delacroce who had every reason to fight, start an internal war, etc., and he didn't. Why? Because he was a true believer.
