Like yours, my hate level depends on the importance of the issue; so I really really hate pseudo-philosophy. This time it’s the Beeb seeking to link physical illness to the concept of free will.

As far as I can see (which on a clear day is forever), this article is a PC attempt to forgive (oh no, not again) people for behaving badly when they get ill. Er, excuse me, but the law of the land does differentiate between the healthy and sick with its rulings on being ‘fit to plead’ and for me that will do. Don’t necessarliy lock up the deviant in a regular jail, just keep him out of (his own) harm’s way. That’s the only concession necessary because the concept of free will is about normal people under normal conditions – not when they are sick or constrained to commit felonies or wha’ever. And your or my deliberate (that is free) decisions about diet, narcotics, social behaviour and sexual preferences are not excuses for lenient treatment from the rest of society. So get over it and find another get-out-of-jail-free card.

I think you are looking at this far too simplistically.
For example, I had a neighbour who was a kind, soft spoken decent chap. He was involved in a car accident where he sustained a head injury. After he was out of hospital his personality was completely changed for about six months until he had fully recovered. He shouted and swore at his wife, in full view of others. He would come into the garden naked and call us over the fence.
Once he had recovered from the accident, he was back to normal and very ashamed of how he had behaved.
We have to make allowances for people who are temporarily ‘altered’.
Definitely, but let’s not pretend that injuries or ‘conditions’ excuse people from their responsibilties. That’s a slippery slope too dangerous to think about.

Actually I think that it’s a slippery slope that does have to be addressed.
I agree with Gazoopi, allowances should be made for those who are ‘altered’ How on earth that’s achieved is beyond me, a cat scan in every court?
