An evil superman, or superman prime, yeah, no shyt. But that isnt "superman" as we know him.
THANK YOU
In that scene, that was so carefully selected to prove this point, shows Superman doing all that shyt to green-as-can-fukking-be heroes that went too damn far. The argument should just end here at the fact that Superman didn't even do anything serious to these guys, other showing them that they don't want it with him the way they were trying to go about it.
You think the methodical, legendary, and oh-so precise Dark Knight is going to even make ONE of those fukking mistakes?
The level of frustration, fear, and emptiness that drove Superman to do what he did at the end wouldn't happen. The trust the two have between one another, paired with the fact that Superman entrusts Bruce with the actual task of STOPPING HIM SHOULD SOMETHING HAPPEN over the powered heroes, should show just how seriously Supes takes Batman.
Bottom line: it's a wrap for Supes, because Clark knows if there's anyone that can stop him, it's Batman.
Bruce got a plan, believe it
