Jon carefully weighed his options. He could keep the priestess around and let her do his dirty work, seeing as she had no scruples whatsoever and claimed to be loyal. But on the other hand, the faith of the old gods was the embodiment of the worship of nature. It was very similar to the old pagan religions. The Faith of the Seven or R'hllor reminded him too much of the thrice-damned headache that was Christianity or Islam. All of them seemed intolerant of magic users, unless they were under their control. As for having someone else do his dirty work or take the blame, that was never truly his style. If he wanted to do something, good or bad, he always did it himself and proudly shouldered the consequences for it.
