I mean, it's pretty much the same as last time. There's a plothole, though; if there are gods watching, why didn't they remove the orb that gave him powers in the first place? And if Ominous has empathy/emotion manipulation, why doesn't he just make everyone happy and content all the time?
It could be because when an orb is given to a mortal, it couldn't be removed. Also, the reason why Ominous couldn't do that is because his powers aren't strong enough to do this and need the power of the Chaos Emeralds in order to increase them. These are just suggestions, so don't take them too seriously. Sorry about that, though.
