@SeeingI: I realize that I didn't complete my Davros thought reading it back now, and I wholeheartedly agree with you. I believe that I was never more haunted as a child than by the character, and that initial fear has always aided each of the portraying actors. So, I don't think I would have even considered to…

I've watched Davros through the years; and, of all the Doctor Who recastings, we should never forgive Eric Roberts as The Master.
