Of course, the situation when a player scores a goal in his own goal will be unpleasant for the bettor who lost money. Even if it is a ridiculous mistake or intentional behavior, it is unlikely to mitigate the bettor's frustration. The only good thing is that such situations are not so frequent, so they are quickly forgotten. Personally, I do not understand people who because of this curse, persecute, etc. this player. Anything happens in life and you need to be ready for any situation.
