Super Freak
Superman was still a good person in this movie, and he proved against the odds to be an amazing hero. He didn't ruin Metropolis and he wasn't proud that it was destroyed. Nor was he proud of killing Zod. Just because he was smiling at the end doesn't mean that he was any less distraught over the destruction. What it means is that he feels no guilt, which he shouldn't. It wasn't his fault.
