You are allowed to appoint a great Rabbi from a few centuries ago the arbiter of permitted thoughts in a millenia old religion. Others aren’t obligated to follow. Contrary to what you might wish to be true, there are a multitude of strains that constitute Orthodox Judaism. As for Hashem’s initial intentions that’s up to his being to decide.
It’s a very easy and simplistic mindset to believe that everything that contradicts what you were raised to believe or adopted later in life, can be explained away with a whisk of the fingers.
“Anyone that disagrees with me (and therein muddying the waters of what constitutes the right approach) must be heavily influenced by desire for forbidden sins, and their thought process must be rendered inconsequential.”
-Imagine if we threw such heinous projections on every one of our great thinkers that said something that wasn’t word-for-word verbatim what his teacher taught him. We’d be very destitute indeed.
It’s the same mindset that leads to any sort of conspiratorial thinking.
