I have read the Guardians extensive obituary on Ian Brady this morning.
There has been a discussion on here about whether Brady was mad or not. According to the obituary, in 1985, partly due to intervention of Lord Longford, Brady was diagnosed as a psychopath and sent to Broadmoor.
A mental health tribunal was set up in 2013, due to Brady's insistence that he be moved from Broadmoor, to a normal prison,. That Tribunal upheld the experts view that Brady was psychotic, paranoid, and had a severe narcissistic personality.
Now, I don't know whether that makes him"mad" in the eye of medicine, but as far as I an concerned, its mad enough for me.
