his conduct, or to adjust his conduct to the requirement of the
law.”

If the mental disorder impairs the cognitive faculties
of the accused, he is not held responsible for his acts.
If insanity affects only emotions and the will, but not
the cognitive faculties, the person is held responsible
for his acts.
Doctrine of Diminished Responsibility
If an unlawful act is committed by a person who is suffering
from some degree of mental illness, should not be treated like
a sane person who committed an unlawful act.
According to this theory, such mentally ill persons have
diminished responsibility.
Punishment for them for commission of an unlawful act
should be less.
