[Man of Steel] Why did General Zod want to terraform Earth into Krypton?

On Earth Kryptonians are literally gods, all he needed was to restart the Kryptonian race on Earth not terraform it. So here is my question did I miss anything that informed his decision?

Zod says something to effect of his entire reason for existing being to protect and defend Krypton. He failed at that the first time, so turning Earth into a new Krypton, as close to the original as possible, was the next best thing he could manage. A chance to bring it back nearly as it was but free of the flaw (weak leadership) that led to the destruction of the original. 

There's also the practical side of it being incredibly dangerous to have an entire planet full of people with the power of Superman. The Kryptonian equivalent of a drunken fistfight would level a city. Imagine if someone tried to attempt a coup exactly like Zod did originally. The destruction would be horrific and probably ruin the planet beyond their ability to fix.

And, whether Zod realises or admits it to himself or not, he also probably wants to make it easier for himself to maintain control. When the entire population are just regular Kryptonians, himself included, then the ones with the weapons and soldiers are the ones with power, and he has all the guns and a loyal army. When everyone can benchpress a mountain or throw a battleship, that gap in power narrows considerably. Sure, he and his soldiers might be able to eventually defeat or contain any unrest that might arise but that would take a lot of time and energy and cause significant collateral damage, circling back to the previous point.
