So, keeping upon the topic - perhaps we need to answer in the binary format: Was Rutherford Mentally Ill? Yes or No -
Now, here I suppose we drift into semantics: but, I would say that sociopaths are mentally ill. I would say that deeply paranoid personality types are mentally ill. I would suggest that persons with a compulsion disorder leading to addiction are mentally ill. Persons delusional enough to suppose the dead are coming to live in their home are mentally ill. There are many forms and degrees of mental illness, but you would have to say that any person suffering from remarkable tendencies of all the above are ill to some degree.
I would further suggest that persons who have such a delusion of granduer that they think they personally caused it to not rain in spain upon the plain, are mentally ill. (all because the government would not let them spout anti-catholic rhetoric - in Spain, of all places, home of the inquisition!) Can you imagine the public outrage that would have followed?
Further, KW, notice that I am not calling Rutherford a murderer. I merely compared some of his career tendencies and mental attitudes to Hitler. However, another poster has rightly pointed out that Rutherford was completely blind to the suffering that he inflicted upon many of his fold in Germany by elevating his anti-government rhetoric to the point that it could not be ignored.
I suppose it could be said that neither Rutherford nor Hitler actually shot or gassed any JWs personally, but they personally set up the stage where this tragedy played itself out. Each with equal guilt, IMHO.
