I watched a video discussing TV and movie adaptations of Superman. The speaker, who is far from being the first one to say this, claimed that Superman killing Zod in "Man of Steel" was murder.
FALSE, FALSE, FALSE!!
The Mosaic Commandment about killing used the Hebrew verb "ratzah," which NEVER EVER meant all instances of slaying equally. "Ratzah" refers ONLY to the killing of an innocent victim, or to killing as personal blood-revenge. The English word "murder" is likewise limited in application. In the "Man of Steel" climax, General Zod was actively trying to murder innocent people; he could not be reasoned with; and he was too powerful for non-lethal subdual to be a realistic solution. As the clear and unprovoked aggressor, Zod's claim to life was morally inferior to the right of his targets to live. He deserved to die; his intended victims DIDN'T deserve to die; and in the circumstances, Superman was in fact OBLIGATED to execute the evildoer.
