Black Adam Retconned a Shazam! Plot Point 

Black Adam retconned a Shazam! plot point, altering the past with a writer's joint.

Black Adam was set to change the hierarchy of power in the DC Universe.

 it apparently did so in a rather negative way.

The wizard Shazam's previous decree made Black Adam evil, but his intentions weren't astray.

He sought power to save his people, enslaved and grey.

But Shazam's words twisted, led Adam away, 

until he fell into the dark side and couldn't stay.

Now he's back, with a new path to pave and a chance to rewrite the story that had been so grave.
