The gods in the society were always imperfect. They messed up in life, they cheated and committed crimes and were sly. The difference between the Greek and other gods and our gods today is that our gods are perfect. They never make mistakes and if we do make a mistake they will punish us. I think that how we think of our gods changed over time because over time we came up with an idea that we have to be perfect. If god is perfect and if we are punished for being imperfect then it gives people a reason to say that they need to be perfect because otherwise god will punish them.
