It's interesting to defense lawyers too, if you can say 'my brain made me do it' you can't be culpable.
Says who?
Of course, the fact that Fred's brain was changed by a tumour is what makes this case interesting and proved how behaviour can be changed by extreme circumstances. But once you accept the fact that brain, beyond our own will, is responsible for behaviour, you can legitimately ask to what extent we are in control of our own actions generally.
Where is your justification for separating the brain from various cognitive processes such as will?
Well rather a lot if you're a believer in the concepts of free will and evil, right and wrong, sin and absolute morality.
Not really.
