In the case of Tate, it teaches you that you can administer a substained beating of over 32 minutes to a 4 year old, rupture her kidneys and spleen, deliver blows hard enough to crack and fracture her skull, collapse a lung, crack a verterbrate and cause her to die during this "play". And you can blame it on copying what you see the wrestlers do on tv as your defense excuse when you are tried for murder.
