Not much to say except what that story described is just wrong in my opinion...period. It shows a level of inhumanity as well as lack of any type of evolvement - I would think even apes treat each other better.
Its one thing to have 'rough' training, but its another to trick someone and then try to maim them.
Yes, to each their own...and they can keep this 'own' to themselves.
