Super Freak
It was huge in the comics because they left it decades before doing it and they only did it due to poor comic sales and to emphasize his importance.
Snyder also used it to show the world how important Superman is, he just did it earlier to progress the story and the need for the league.
You are doing what ironwez is doing and basing what is right on how you think it should play out because of other interpretations.
In a 5 part movie arc, that brings at least 6 main superhero characters together plus a Steppenwolf invasion and then a Darkseid invasion when is the best time to kill off Superman?
That is my opinion T800 and I am gonna stick to it. I would kill him off after the huge Darkseid story arc when you actually care about Superman. Also Synder tried to show how important Superman is but he failed because the character was not developed enough. He bearly showed up in the DC universe and he bearly had anything to do and did anything. He had one movie and he just died in his second.
