That's true but he was turned into a human before that happened and it was a long drop. I doubt superman had a giant feather bed at the bottom of the shaft.
This brings up another question. Why did superman do that to them? Once they were human all he had to do was drop them off in prison with Lex. I doubt superman would willingly kill anybody if he didn't have to.

Technically we never see Zod actually die, he falls into the mist we assume he's dead.

Supermans villains, especially Zod and Braniac have a tendancy to come back from certain death.
^Exactly!
I will also add to that the fact that they can be clone. Luthor could try to revive Zod again...but that's pure speculation.
