In "Man of Steel," there was some controversy over Superman killing General Zod. Most Superman fans are aware of that he doesn't believe that death is necessary. The movie's screenwriter explains and he eventually discards the unwritten 'no killing' rule.

David S. Goyer, screenwriter for 'Man of Steel' recently spoke at the BAFTA and BFI Screenwriter's Lecture. It was the perfect venue to discuss the sensitive topic.

Superman was supposed to embody the ideals of our society, although previously, it was perceived as 'The American Way' (specifically during The Cold War when Superman was even accused of being political propaganda). He was supposed to do no wrong, and stand above the moral weaknesses of the ordinary man. He did not just have superhuman strength, he was 'super' in every aspect.

Goyer admits that they anticipated a reaction: "We were pretty sure that was going to be controversial. It's not like we were deluding ourselves, and we weren't just doing it to be cool. We felt, in the case of Zod, we wanted to put the character in an impossible situation and make an impossible choice."

The renowned screenwriter has very logical justifications for the ending:  "So the situation was, Zod says 'I'm not going to stop until you kill me or I kill you.' The reality is no prison on the planet could hold him and in our film Superman can't fly to the moon, and we didn't want to come up with that crutch."

Another point that most critics seem to forget about the film-the symbol on his chest is not an 'S' and Henry Cavill was playing an alien named Kal-el. At that point, Superman as we know it did not exist yet. Goyer elaborates:  "Also our movie was in a way Superman Begins, he's not really Superman until the end of the film. We wanted him to have had that experience of having taken a life and carry that through onto the next films. Because he's Superman and because people idolise him he will have to hold himself to a higher standard."

Kal-el has blood on his hands. As he turns into Superman, he has certain realizations. Will he stop killing? It's a Zack Snyder movie, remember "300?"

Let's see. Rumors say the release date has been moved from 2015-to 2014.
