I think 'wired' is the wrong word to use as it implies we're all kind of like that which isn't true. People who judge other people more harshly for their actions generally judge themselves pretty harshly too. The faults we see most in others are the faults we see in ourselves the most. If we were really wired this way than cognitive behavioral therapy wouldn't work, but I guess that depends on your definition of 'wired'. This is more a product of low self esteem than how we are 'wired'. I think the social conditions which are creating a society of low self esteem should be under a microscope instead.
