Did this experiment by the psychologists involved in working on the triplets described in the movie, Three Identical Strangers, have a more sinister motive than what was purported to be simply a study of parental influence on childhood development?

This did have a sinister underpinning because it was done by individuals who had links to the intelligence agencies who were involved in many mind control experiments and were using the inflicting of trauma to alter the mind, and determine the ability to create responses within their subjects that could have military potential. They were interested in all aspects of influence on development of the personality and because the variables of parental influence were in the mix this experiment was, in fact, conceived to track that, primarily. This was part of the answer here for the reason he ended up taking his life, because he was met with more difficult parental treatment and this is what was stirred up and amplified within him by his spirit meddler attachment, and used as leverage to increase his suffering and torment, pushing him over the edge in the end, to take his life. The experiment, in the context of others of a more clandestine kind, was less problematical because they were, at least, choosing families to rear these young people and not keep them institutionalized as a kind of prisoner. But, to separate the triplets from one another was non-divine even though the parents may not have been in a position to raise them. So, it was done for selfish reasons to serve the needs of the experimenters and their darker collaborators. And so, this will have quite a karmic negative influence for all involved.
