I agree, that there is no need to kick him while he is down. I think the humane thing would be to do nothing. Just like we do for every other sick person we've never heard of. Wishing your enemies to get well soon adds nothing. If he had a stress-induced event, then it was self inflicted and his choice. He choose to not make his health a priority. Treat him like an adult. There are consequences for his actions, even if these aren't the actions we would like him to suffer the consequences for.
