I consider victory over the Watchtower as being completely independent of any and all people remotely involved with the WT.
Victory over the JW's would't be it's total disbanding. Major cults don't disband in that manner. It's usually a very slow process. The cult will collapse on it's own like the Millerites or undergo a serious Glastnost like the RLDS. From how everything is shaping up for them, they're clearly not going to survive as they are.
Rather, our being here is a part of victory over the WT, the fact that we're free of their psychological control and how they have one less educated person to control. In a way, we're leading to the WT's eventual dissolving or Glastnost.
