I'm far more used to watching the Donner cut, in which the Zryptonian villains survive (and never leave the Phantom Zone at all, thanks to time travel). And even in the theatrical cut, it's left ambiguous as to what happened to Zod and the others. However, I do think that the scene should have played out differently, as it does look like Superman could be killing them.
But in the end, what does it matter what happened in Superman 2? Just because it happened very few times before, either in previous films or in the comics (which are not always the pinnacle of storytelling for these characters and can sometimes be improved upon), doesn't validate it happening again.
