He wanted to inherit Rutherford's kingdom. It would appear politic or to use JW terminology,"theocratic" for him to abolish the monetary shares in the society in 1945 but would it not be in his financial and power interests to honour the original investments?

Being nominated is perceived as a privilege and so these voters are basically yes men to whatever the directors propose.
