An interesting character for sure. Learning something new every day.
Many people view him as a man who genuinely wish to help the country.
Heck there are even conspiracy theorist who believe that he cooperate with Anti Japanese resistant so that no matter which side win the war Thailand will get out of it relatively light. But I am not sure how true that is.
