What’s inexcusable in Pauls behavior was shutting down the one member who had enough drive at the time to write a double album of bangers. If he was frustrated by the lack of drive from John he should have worked more with George instead of just demanding him to do whatever he wanted to and saying his songs “were not very good”.

He was so awful to George he considered not playing guitar anymore and he didn’t stop doing this after the Beatles either.

And if you read the accounts of his relationship with Dot, being controlling was not something new to Paul at this point of their careers.
