At the same time, one must be at least somewhat convinced that what someone states is indeed from their informed conscience.  That is where considerable room for doubting the involvement of Cardinal Burke's conscience exists, as he has a long and revealing pattern of opposing the pope on every significant matter possible.  That is not the exercise of conscience: it is the use of a vindictive predisposition cloaked in "theological purity."  The other three cardinals I know almost nothing about, so I leave them to others to figure out.
