I'm not sure abhorent thought process brought on by thinking more of yourself than others is 'illness'
It may lead to more extreme thought/action but the root cause is lack of self-control or being able to impose self-restraint or limits
This is developed over years from a young age through guidance and imposed discipline
Learning to accept you most likely will not get all you want
Cancer is an illness but does not lead to mass homicide
Mental 'illness' needs catagorized differently since it can have severe consequences for the individual and society
What is difference between what this guy did and a suicide bomber?
Documentation, he could afford to be treated
The poor terrorist could not
But both results are the same
Both are obviously 'crazy' and have a disturbed/distorted thought process
ANYONE who kills dozens for ANY reason is not mentally healthy
Both are 'evil'
Why are people afraid to say this?
