Justifying Electroshock

I came across this special quote:

"Thus a patient who chose to undergo some mild brain damage, which would result in mild persistent memory deficits, in order to escape from severe psychic pain that could not be relieved in any other way would not be making an inherently irrational decision."

(‘ECT and Special Problems of Informed Consent,’ Culver, Ferrell & Green,
American Journal of Psychiatry, 137: 1980)
