There are always two sides to a story, and things aren’t always as they appear. This requires a strong level of discernment in those who have the power to affect what happens in response, and a responsibility for those in positions of power to take a deeper look as they can impact how others see the situation. Drawing conclusions with surface-level interpretations can be dangerous.
For someone like Superman — a being of incredible strength, yes, but more importantly, a being with a tremendous amount of authoritative power — it is paramount for him to make sure he thinks before he acts. The story of Superman’s first time encountering Mari "Vixen" McCabe is a great example of his judgment in situations that reside in a gray area.
Vixen is all about protecting wildlife by all means necessary, legally or illegally. In Action Comics #521, she steals some fur coats, driving them — and the van they’re in — into a river. She leaves the scene of the crime looking rather suspect, so when Superman happens upon it before tracking her down, it appears to be a robbery.
Superman is told that the furs' original owner takes part in the poaching of endangered species, and he refrains from telling the officer who was responsible.
The next day, Clark Kent and Lana Lang are called in for a briefing on an assignment to India to cover the fur-poaching in the country, after a friend of Vixen’s convinced the editor how important of a story this was to cover. Vixen felt it was extremely important for American reporters to cover this story, knowing it would shine a light on such a heinous crime. Lana Lang at one point comments on how un-newsworthy this kind of story is, which gives insight as to why Vixen may have gone about things the way she did.
When he confronts Vixen before she can make her move, he takes the time to get an explanation instead of hauling her off for stealing the furs in the first place. He understands why she went about things the way she did and holds no judgment because at the end of the day the true villain in all of this is the store owner. He leaves Vixen to deal with him accordingly.
Superman had every reason to view Vixen as a criminal but doesn’t. Instead, he acknowledges the good Samaritan qualities in her, a hero in her own right.
