“Every form of addiction is bad, no matter whether the narcotic be alcohol or morphine or idealism.”

It's always the "True Believers" who cause all the trouble.

Jung did turn to his treatment of alcoholics with religious experience as a last resort. Bringing about AA. He also observed the importance of religion to the individual, and how the state as with Germany became the god, and practiced Threskeia religion, marginalizing the individual.

bad for who ? "Every" is a very limiting term. Who's measuring standard is here defining "bad".
