In the most controversial scene in the DCEU Man of Steel movie, Superman kills General Zod, though one famous DC Comics writer feels that this moment was far better than its comic counterpart. General Zod, as a Kryptonian criminal, is one of Superman’s most dangerous enemies, as he possesses the same powers as Superman himself, thanks to his exposure to yellow solar radiation. With this in mind, it is extremely difficult to overpower, let alone contain Zod, who feels no compassion for humanity like Superman. Unsurprisingly, there are multiple DC universes in which Superman kills Zod, albeit reluctantly.
