Didn't Rutherford at one time call the IBSA members who wouldn't follow him who rather wanted to stick to Russell's teachings the Evil Slave ?
One thing one can honestly say about Rutherford he had great balls to call himself the chosen one (FDSL) by god and demonize others who wouldn't accept his professed doctrines .
A false prophet apostate calling other people/organizations the evil slave, how ironic !
