He definitely wanted to die. Probably would have killed himself anyway if he managed to kill Superman. His sole purpose at that point was to destroy Superman, maybe he realized that making the boy scout kill was another way of destroying him.
If he managed to kill Clark, Zod would have killed everyone on the planet first. Then maybe himself.
