David Davis, Bigelow v. Berkshire Life Insurance Company…
“ As the line between sanity and insanity is often shadowy and difficult to define, this company thought proper to take the subject from the domain of controversy, and by express stipulation preclude all liability by reason of the death of the insured by his own act, whether he was at the time a responsible moral agent or not. Nothing can be clearer than that the words, 'sane or insane,' were introduced for the purpose of excepting from the operation of the policy any intended self-destruction, whether the insured was of sound mind or in a state of insanity. ”
