Shazam (Injustice)

In the parallel world seen in the DC Video Game "Injustice Gods Among Us" Shazam is one of many superheroes who have joined Superman's Regime, his hero-worship of Superman making him assume that Superman must be justified in his actions. But as time passes, this certainty begins to disappear as more and more Shazam starts to doubt the justness of the Regime's cause.

History
Regime Shazam first appears alongside Regime Flash as one of the emissaries to Atlantis. When Aquaman (unbeknownst to them an Aquaman from a different universe) rejects the Regime's treaty with Atlantis, a fight breaks out. After defeating the Flash, Aquaman bests Shazam. The two are later seen again on the Watchtower, discussing Superman's recent actions and plans to have Batman executed. Shazam admits that he joined the Regime because it made sense to him at first but is now uncertain as to whether or not they're right anymore, remembering Superman's earlier murdering Green Arrow. The two's conversation is interrupted when Flash is alerted to Deathstroke's presence. Shazam is the first to fight him and is defeated, Deathstroke noting afterwards that he's "still just a kid".

Regime Shazam next appears in Lex Luthor's chapter, attacking him and expressing confusion at Luthor's apparent loyalty to the Insurgency. Luthor explains that he's been with the Insurgency "since the day Superman decided to herd them like sheep". Shazam attempts to defend Superman's actions, but Luthor is unmoved. Though Luthor bests him, Shazam is able to damage Luthor's armor, foiling his plan to stop Superman. When Superman murders Luthor and then snaps upon realizing that the world's population is afraid of him, Shazam is left uncertain and confused. Later, when a now completely unhinged Superman decides to exact vengeance on Metropolis and Gotham City, Shazam objects, only for Superman to then murder him on the spot. His cold-blooded killing of Shazam prompts the Flash to defect, realizing that Shazam was right and that the Regime has gone too far.

Trivia
Superman's killing Shazam is widely considered to be the Man of Steel's Moral Event Horizon crossing, the act made even worse when one remembers that Shazam is a teenager in an adult's body.
