I must say that I find this very disturbing. No matter whatever they claim to be, or whatever they claim their motives are, their behaviour indicates directly the opposite. The greys often claim that they are very spiritual creatures and that everthing is done for the abductees benefit. I think this is simply a lie. The abductee's lives are often completely ruined.
Relationships are broken-up and contact with the outside world diminishes.
Many abductees suffer from severe stress and mental problems, as a result of the abduction. They suppress the abductee's free will and privacy. They follow their own agenda, showing no interest in the lives of the abductees, etc. So, even though they claim that they care for the abductees and that they do all that they do in the name of spiritual progress, their behaviour actually indicates otherwise. What they had remembered as a loving and joyful experience, later appeared to have been an extremely dreadful experience.
