Some think Kaido is done?
Kaido has already lost 7 times as a pirate and that didn't stop him but this 8th lost is different. He must stop now because of feelings. Don't want to hurt the fanboys feelings.
We all knew Luffy would get a win in against Kaido. Kaido beat Luffy 4 times. Oda officially declared Kaido the winner so Luffy receiving a win doesn't mean it's over for Kaido.
Remember, Luffy was beat by Kaido, knocked unconscious, knocked off the rooftop top and didn't return for 11 chapters. 6 of those chapters he was unconscious.
The government failed to execute Kaido 40 times and he survived being tortured over a 1,000 time and have only received 2 scars on his body.
No, magma won't kill him.
