I think deep down Russell made stuff up to increase circulation to make his printing business profitable. He no doubt chose contributors/writers who he felt would increase sales,, it was a business so his choice of what he wrote and who he choose as writers had a bottom line: profitability. Lets not forget that he at a young age had already increased his father's clothing business to a chain of stores, and printing religious literature was just another business venture to him but also gave vent to his egomania thinking that he was a special person doing the Lord's work in warning those facing destruction.
It's easy to see that the bottom line is money and not purity and truth for what the Watchtower Corporation publishes.
