As much as I would hate that god for disrupting a world that is on peace for a long time... stagnation isn't really the best thing also, you sometimes have to shake the jar to mix the things inside it... not to mention being a god would also 'cause boredom watching over paint dry compared to watching conflict...
But at the end of the day, still begs the question why that god wanted a revolution; is it because of boredom? or for advancing the people in that world... honestly based on the god's lines it's most probably because of boredom
