The Three Were Once Good?

There are two opinions on the status of Abi Bakr, Umar and Uthmaan from the 12er Shia point of view. 1) They were monafiqeen since day one 2) They became monafiqeen since the Prophet (pbuh) passed away. The first opinion without a doubt contradicts the Quran. However, for the second opinion there is no proof in the 12er Shia ahadith books.
