Dear lord and Rasoul,
People in the West are also capable of cruelty to one another, only in a different form. Here in England we here of mothers stabbing their own children and burying them, while others walk the streets and stab people just because they can.
I was making a general point about mankind. The potential for cruelty is always there, unfortunately.
In a funny sort of way, perhaps it IS due to our superior mental capabilities!
