Ethics
The horrible events of MKUltra completely break common moral codes. Experimenting on people with dangerous, not fully tested drugs, is dangerous, and very unacceptable, also using kids, cancer patients and defenceless people is pushing the boundaries. Merely having the idea of locking up people and torturing them is already far enough, so those who actually did, are quite merciless and cold blooded. They spent part of their lives looking down on human lives and experimenting on people like they have no mind, which seems to be one of the worst things to do.
