In the article they explain that the doctor increased only the dosage of one drug - Oseltamivir. That drug is better known as Tamiflu, which doesn’t relate to your conjecture about the Thai doctor’s state of mind.

I’m strongly inclined to believe the other commenters in this thread.

“We have been following international practices, but the doctor increased the dosage of one of the drugs,” said Somsak Akkslim, director-general of the Medical Services Department, referring to the flu medicine Oseltamivir.
