OK cool so it's 2 Batmans gotcha.
Breh it's not 2 batman's. Clark, much like Bruce, had to learn lessons to become the hero we know him to be. Go back and read the old superman comics, he was quite the b*stard and not the clean cut hero everyone sees him as now. So in order to truly show how a character obtains his morals and his attributes, you put him in a situation where he has to grow from which is exactly what they did. So if the new movie starts and he's on some "Nah no killing" which is a rule batman also has but he's always willing to flirt with that rule. That's how you make the contrast between the two. Superman has to be able to grow and develop just like any other character
