I'm not reaching anywhere here. Batman vowing not to kill anyone is as holy to him as the preservation of life is to Superman.
I ain't even gonna respond to the other posts. If you still don't comprehend the point I'm making (as well as flat-out ignoring half the examples I'm giving), I'm not wasting my time any further.
Instead I leave you all with a download link to Action Comics 775, for anyone who dares to see, or simply wonders, what a proper interpretation of a modern day Superman looks like.

You can unpack the file with WinRar and view the images independently, or download the free program CDisplay to read it.
