Before you make an idiotic remark saying I don't know what I'm talking about, I'll let you know that my father was an esteemed scientist on Krypton who is quite adept in all fields of The Phantom Zone. Now I'll begin. I see a lot of pseudo military theories are set in stone when any real Kryptonian knows that there's always a chance that you'll commit genocide on the human race. Most Houses would even be glad to find that they've ruined a batch of glorious cloning since it allows them to get closer to the true perfection of the bloodlines. It's pretty clear most of you know nothing about the codex or what Zod is trying to accomplish, and saying that his ideals are perfect is a testament to that. Atlanteans used to think the surface world was for cretins. The Green Lantern Corps used to think they were the fgt police of the universe, and you could even test the anti life equation to prove this theory. Speedsters used to think that anyone who couldn't handle the Speedforce were pussies. Martians used to believe that you could play with fire. My point is that the art of saving the human race isn't something that has been perfected, even the best superheros cannot predict Joker.
