Pazuzu did kill people, not in the original Exorcist but I believe Pazuzu did kill in sequels and in Legion.

Satan from Touched By An Angel can't personally kill anyone due to God forbidding it, it's not due to Satan being against killing (he'd love to kill, he's just forbidden from personally doing so as God has decreed Satan has power to corrupt but not outright kill His creations)

Hitler's a debatable one, I find it hard to believe Hitler never personally killed anyone in his career.. though I could be wrong.
