"Doctors and judges made him die."
-They tied a ligature around his neck?
No: the damage he did to himself "made him die". Doctors and machines gave him an artificial reprieve from that in hope of some recovery, but he'd done the job too well.
As to your imprudent question "Why is "hope of recovery" a criterion?" That would be because his parents considered it a criterion. As above they went to the courts because formal brain stem testing could not be done therefore a chance remained he just might not be brain dead: ergo there was hope of a recovery.
Unfortunately the scans showing necrosis said otherwise.
