They should have just done genetic modifications of humans in the embryo before they were born to create infinite super humans. You're telling me a Tier 2 civilization didn't have the technology to do genetic modifications in the embryo stage? They had to do genetic experiments on children already born? Stupid convoluted story.

the unsc have to follow the rules, theres a reason all the spartan participants all voluntered for it.

modifying an unborn embry is like altering someone not borns life which is wrong
