In case people don't have a good understanding of what a supermax is, it is torture.

295. Thanks for the serious reply.

I appreciate the concerns you raise. In fact, I think that there should be separate facilities for all prisoners who are diagnosed psychopaths. They wreak havoc in prisons.

Nevertheless, I think you might be overlooking the fact that there are various ways to avoid the psychological problems associated with social isolation without risking the sort of dangerous communications you are talking about. Indeed, having contact only with prison staff is fine when the contact is sufficient to meet the basic psychological needs of the inmate. Even playing online games with anonymous players can be useful psychologically. (Of course, you would need to make sure surfing the web is not a possibility.) There is no perfect solution and some prisoners will not adapt well to any situation that severely restricts their communications. But we need to try our best to prevent dangerous communications while meeting the basic psychological needs of the inmates.
