Right psychology, as I understand it, sees that one person’s power over another conscious and rationally volitional person is sick.* This is an area where human psychological health and the moral good are identical. Deliberate force, whether it is emotional, cognitive or physical, is destructive to the autonomous and "free" workings of the human mind (free will is a phenomenon where appearance is the reality at the behavioral level). It is, of course, not the only harm that happens to the holistic self. Trauma can be unintentional force that overwhelms the brain. Emotional neglect and absence of empathy starve the psyche, which needs experiential, cognitive and emotional stimulation, most especially love. Deliberate force is not a different category of harm. It is unique, however, in humankind's assumption that it is right and good.

* This is admittedly a purist idea. Society, very likely, could never be without some legally sanctioned and codified force against some or all of its citizens. An anarcho-libertarian society is destined to be impossible. Nevertheless, the concept that force is injurious to the human mind does, I believe, make sense when applied to child-rearing, and underlies Dr. Thomas Gordon's classic Parent Effectiveness Training, which I believe is one of the best guides to parenting. Respecting the child's mental and emotional processes is the theme behind Gordon's key ideas, which include the well-known "I statement," active listening, "who owns the problem" (adjuring the parent not to interfere in the child's capacity to solve his own problems), and more.
** If you are starving in the wilderness, you may have to eat a pregnant wasp or a pantsuit-wearing caterpillar (http://www.businessinsider.com/un-eating-insects-to-solve-world-hunger-2013-5). I see the upcoming presidential election in this spirit. The thought of contributing, by inaction, to the triumph of an entirely pathological botch, Donald Trump, causes me to compromise my principle of non-involvement. I will be voting.
