evil does not exist. hurtful actions are caused by malfunctioning brains and not an evil spirit. actions are caused by our neuronal networks.
Realist
If your assumptiom stated above is to be considered factual then I would submit that bueaty does not exist, or color for that matter as they are but the interpretation of electrical impulses, by our brains, from the stimulation of the eye by rays of light.
Music would therefore be nonexistant as well as it is just varying sound wavws impacting the ear drum and again translated by our brain into recognizable and enjoyable stimuli.
Just because a certain something can be reduced to its most basic scientific causal and effectual definition does not make it nonexistant. Nor does it nulify the termanology associated it by society, be they "educated" or "lay".
Why you have chosen to dismiss abhorant behavior using the excuse of misfiring nuerons or some such biological defect, is beyond me and I feel a rather flimsy argument base.
If "evil doers" are that mentaly defective, removal from the gene pool would seem the "logical" course of action, be it through detention or execution.
Myself I would choose the latter and save the taxpayer the cost of attempting to rehabilitate a mentaly defective, violent, consciousless, cold hearted, drug using, drunk driving, self centerd monster.
