Theory on how Arthur Harrow Left Khonshu and Started to Free Ammit

What if as Khonshus fist Harrow thought he was doing the right thing due to his strong sense of morality but than after seeing so many horrible scenes left from Khonshus victims or hearing of and seeing the horrible crimes committed that he eventually starts to think it should be dealt with prior to the act being committed as it would prevent all the horrible things he's seen as Khonshus fist. As he's dealing Khonshus vengeance and growing sick of the horrible things he's seeing he hears about Ammit from Khonshu trying to prevent her from being awakened. As they're searching for Ammit they come across the Cane given to Ammits first Avatar. The power in the Cane is what could have been able to Free Harrow from Khonshus control without him dying (Since it seems Khonshus always threatening mark with going back on their contact which implies he would die) and since he's grown sick of the things he's seen as Khonshus fist he wants to prevent them from happening and therefore starts searching for The Scarab that he would have learnt about from Khonshu in their hunt for Trying to stop Ammit from being awakened.
