Again, the the benevolent god-figure Jor-El who sends his only son to Earth to be a beacon of inspiration was an invention of the Donner movie and was done to both make the Superman movie appeal to general audiences in America at the time, as well as a way to convince Brando to be Jor-El (since he'd basically be playing God).
Prior to the Donner movie, Kryptonian society in the comics evolved into a very strictly and arrogant scientific society that refused to listen to Jor-El's warnings about the planet's core about to explode. Jor-El simply sent Kal-El to Earth to save him from the destruction of the planet; the whole "light to show the way" BS was invented by the Donner movie.
Superman's goodness came not from Jor-El sending him to be a beacon, but because he was raised by two kind farmers in Kansas. Gunn's Superman understood that better than any Superman movie before it, and people are mad because it didn't follow the Christ metaphor that Donner invented fifty years ago.
