Obviously, something changed between the time that the God of Darkness created Grimm and the present day on Remnant. One possible thing that changed is that the Grimm have someone telling them what to do: Salem. Which leaves questions as to where the hell she came from and how she's ordering the Grimm around.

The way Grimm behaved in the story about the deity brothers and the way that Humans have observed Grimm behaving could be different not because of inconsistency or the story about the deity brothers being wrong, but because something changed.
