Like Hiku90 said, but further. He knocked Goku out because his selfishness (power boost to surpass Goku) created Buu, and he was taking sole responsibility for it. He didn't want Goku to die over a mistake that he was accountable for.

We know that this is what he meant as in the manga, he tells Goku something like, 'We can settle this after I defeat Buu', then says, "If I survive."
