Is anyone aware of any audio of Palpatine uttering the phrase “kill him” other than in reference to Dooku in ROTS?

The novelization of TFA describes an inner voice of rage saying these words to Rey as she stands victorious over Kylo Ren. Whether it meant this originally or not, one naturally infers Palpatine at this point.

I’d like to at least play with adding that line, but the delivery in ROTS sounds almost casual.

I don’t have a perfect memory, but I don’t recall the Emperor saying that line in TROS.
