The fact that Snyder thinks Watchman is “how heroes should be” is one of his most profound failings as the DCEU shepherd, and shows that he doesn’t understand the work. Watchman is about how “superheroes” flat out would not work in the “real world”. They’d be mentally ill or far too removed from humanity “realistically”. And Snyder clearly doesn’t understand DKR beyond ripping off its imagery considering he thinks Batman kills throughout that story and tried to use DKR, a story where Batman snaps a gun in half in the climax because he hated them so much, to justify Batman mowing down guys in BvS and JL.
