DUE to medical condition…durr…
Simple scenario: A really horrible crime gets done. Use your imagination because I’m in no mood to write up a titilating scenario. But let’s just say it’s a disturbingly aggravated event ending in a protracted homicide.
Suspect is nabbed, confesses all and has no remorse at all. Just for grins, an MRI is performed and some kind of weevil or something is found in the guy’s brain. Interestingly, the evil weevil is irritating a part of the brain known to control decision-making, behaviors, morality, etc. A number of well-respected neurologists all agree the bug could well have caused the abnormal behavior, and that its removal would restore the guy to “normal.” Weevil is removed and normal brain function is restored. Suspect is crushed by what he’s done, and can only say, “It seemed like the right thing to do at the time.” The brain damage is not permanent.
Do you want the guy to pay for the crime?
Do you give the guy a pass?
Explanation of your answer would make things more interesting.
