All i suggested was a simple thing that will avoid this kind of behavior in the future, its not a rule or affecting the way somebody plays.
i'm not complaining about something, im trying to find a solution instead of trying to change the persons attitude.
And to answer to your example, if we were living in a world that stealing and killing is not a crime then yes we would have way more thiefs and murderers.
Thats why we apply rules for everyone and still you can see there are people killing and stealing, thats why we 'lock our houses' to keep us safe from them.
The ethics ,morals and perspective of each person are different.
