Why I can't say that I agree with a 11 year old playing an online game rated for +16 it's up to their parents to make that decision, not me. I played Mortal Kombat when I was young and when I take care of my little nephew there are games that I do not allow him to play and others that I do (Mostly the LEGO games is what he likes and I allow). So it's not really my call to judge his education.
I do feel sorry for him because he was naive. Some children are naive when they are 7 others when they are 11 or 15. Some people may say this was a lesson but I really believe there are other ways to learn a lesson without causing such frustration to a child. I almost believe he was not even fully aware of what he was doing and I can see some social pressure between these kids with videogames these days. Same when they all want to be max prestige in a Call of Duty game so they do boosting sessions and try similar things. It's not different for liking to show their brand new shoes/phone in school, these are just new and modern ways to be popular/cool around their own group. "I am level 32 on Destiny, I am max prestige on COD, I have a 2.0 K/D, and you don't" etc.
Violence is never an option in my opinion so I do not agree with some GAFfers in here for wishing any sort of violent punishment to the man who did this to this child. However, I do have to wonder what are you doing with your life if you are a 38 year old man, sitting at home, playing a videogame in order to upset and lie to children online. To be honest, it's even a bit sad and I will never understand these people.
