You can also destroy the statue if you follow the electric wires attached to the statue there are three electric boxes behind wood panels. After electrifying the second one he will attack you. Once you kill him you can grab the sword and speak to the voice. Electrify the final box and it will fry the statue and anger the voice. Not sure what consequences this will have later on but considering I don't trust the voice and don't want to help it this is the option I went with.
