Diana is further powerful than Juliette. Moreover, I find myself very inclined to believe that Juliette will find her end at Diana's hands.

Clearly, I'm not sure about that, I'm just speculating, but I'm even more inclined to have almost sure that Kenneth will surely find his death in Diana's will... and, ergo, her power.
