yes and no? we haven't seen or heard from god in the show, so all we have to go on is our own disbelief and the narrative of a jilted son and wife. he could be a giant dick, or he could be trying to teach lucifer to grow. until we ever get an actual glimpse of or discussion with god in the show, we can't tell, and i'm a huge luci-fan and pet his poor broken heart every day.
