No, I don't. What happened in Jonestown is not happening in the KH. For instance, from the beginning, Jones inserted the idea that they may all have to die for their ideology. He practiced a long series of White Nights, where everyone would be called in to drink the koolaid. They practiced over and over. They were isolated, and had no other options. They were also malnourished, so their brains could not properly process information. While isolated, with no help, if anyone objected to Jone's teachings---they would be taken away and reeducated in a medical facility. Also they were constantly tested. Decoys would express doubts, and if the person they talked to, didn't turn them in, then THEY were in trouble.
Yes, JW's are expected to tell on each other---but I don't believe they are habitually set up and the "re-educated". The paranoia in Jonestown was very unlike the paranoia at the KH.
Now I know this post could be followed up with insistence on the similarities--and you'd have a point. However degree does matter---the mix is not here for this to happen on wide scale at a KH. First off---suicide is wrong---period. That is the teaching. Jones did not have such a teaching and trained his followers for an extended time to commit suicide. The dynamic would have to seriously change at the KH for quite a while to lead to something like this.
Again---i recognize certain elements---but I don't want to cheapen what happened in Jonestown, the same as i don't want to cheapen what is happening with the WT. Those people could not walk away. Their environment was fully controlled. They had no outside contact. They truly were at the mercy of Jones. And they expected to die at any moment and were ever prepared to committ suicide. And keep in mind---this was not just mass suicide---it was murder/suicide. Plenty objected in the end--so they were also willing to murder for their beliefs. I don't know any JW that is willing to go that far.
