Now look at them: 1. He did not do anything without consulting Lovel, or failed in anything without expecting and fearing his admonishing.（original） 2. He did not do anything without consulting Lovel, he did not fail in anything without expecting and not fearing Lovel's admonishing.(my guess) 3. He did not do anything without consulting Lovel, and he did not be successful in anything if he did not expect or he did not fear Lovel's admonishing.(my guess) Question: Which is grammatically correct?
