Difficult question!
Looking at my own pocket I want losers to be protected as much as possible! One way or another they are the ones that got to feed me.
If one then simply concludes that I am never on the side of winners, may it be successful gamblers or bookmakers, that is not really true, as I obviously do not like to see happen what happens to others that may as well happen to me.
Having said all this I am convinced that the majority likes to see others from time to time get into trouble. Often I just cannot believe some posters being on a book's side. It must have a lot to do with jealousy.
