gildarts may have survived and brain/zeros wound is significant smaller, but cobra has poison-powers. it would have killed natsu, who has a stronger resistance to poison than normal humans (laxus said something like that), and he wasnt even bleeding (he just inhalated the poision). brain got the poison straight to the blood.
