It's not exactly the same. There's no guarantee that Dent would have killed Gordon's son. He was flipping the coin to decide, which turned up heads if I recall correctly when it fell on the floor after Batman tackled him. Zod, on the other hand, had every intent to murder those people and would have if Superman hadn't intervened.
