Most of us at a given time display qualities of "a sociopath", it's simply a question of degree. I'm perhaps 35% sociopathic most of the time, occasionaly more, occasionaly less. To label another a sociopath would be ignoring my own shortcomings.
There is as far as I can experience in the DMT state, no moral imperatives of any kind, just an overiding emphasis on paying attention to the deeply embeded and cryptic message . If anything, I'd say the full spectrum sociopath could get a lot out of it. My own trips definately have a devilish tangent to most of them and I quite like that, providing I can keep a lid on the fear factor.
I'm refering here to the vaporised freebase route. The couple times I've done Aya or Pharma, it's been totaly different as there does indeed seem to be (somewhat) of an underlying moral imperative with that. Maybe a resolute "sociopath" would have some problems with the Ayhauasca experience.
