I do not think I would use the word evil of R&F JW's.
I think they are very ready to do evil acts at the bidding of their evil masters, i.e shunning, denying themselves, or worse their children access to a Blood Transfusion etc etc
In mitigation they do these things because they are both deluded and misguided, but as I said above, they bear heavy responsibility for their masters being able to hold such influence over millions, without their support it would not happen.
Every time a JW steps in to a Kingdom Hall, he or she is giving a seeming legitamacy to the Leadership, who are Evil.
