I was thinkin earlier about Clark's whole aversion to killing for any reason and it just seemed wrong. He and Bruce both feel it's taking the easy way out to kill an enemy and there are other ways to solve problems, which obviously holds some weight and is understandable, but in light of the whole Max Lord Sacrifice arc, you would think they would side with Diana for doing what she did. It's not like disagreeing with the death penalty, which takes into account jury error, appeals and corruption. The stuff the characters deal with is pretty cut and dry. Is there any reason why the World's Finest should never kill? The Phantom Zone obviously ain't doin the job. Ask Zod, Non and Ursa. If they really wanna be heroes, the greater good may call for a suspension of their personal moral fibers.
