Pathological Ones have flipped to the dark side of their orderly, fair-minded ways and can be openly self-righteous, intolerant, cruel, and rigid. Because they are vainly trying to hold onto the rigid rules that once helped them feel safe in a dangerous and corrupt word, they often become obsessed, controlling, and compulsive. They attempt to force themselves — and everyone else — into an extremely narrow box of acceptable behaviors or beliefs. Anyone who resists or steadfastly remains unwilling to live in the Ones' narrow box of propriety often warrants condemnation and punishment.
When they've gone off the deep end into true pathology, Ones can get locked into absolutes and become increasingly intractable — refusing to bend, or mend, their minds or their ways. They can do nothing wrong; everyone else can do nothing right. Because they feel so conflicted inside, they obsess about the failings, or sins, of others. They may even secretly fantasize about administering harsh punishment and believe, on some dark level, that doing so will finally purge them of their own sins.
As such, dysfunctional Ones typically hide behind religious, legal, cultural, or moral codes to control their own behavior, but they also use these same pure and well-intentioned structures to crucify perceived dissenters. Whatever warmth healthy Ones once had is now gone, and they coolly and calmly rationalize their beliefs to the point of hypocrisy. For example, they may preach equality but typically downgrade anyone not within their fold and abiding by its superior moral codes. And they can be very willing to resort to ruling over someone in order to convert them to the one right way.
Going back in history, you could cite the Franciscans' annihilation of Native Americans as an example of a One religion foisting its beliefs on identified heathens. They virtually imprisoned the Native Americans and forced them to surrender their own very sacred beliefs and accept what those Ones considered the one and only proper religion — Franciscan theology.
The more tightly wound pathological Ones become, the closer they move toward total collapse — it's all or nothing, dark or light, saint or sinner. When they're at the end of their rope and can no longer control their own forbidden impulses, pathological Ones fall sway to abrupt, irrational behavior, breaking their own rules in humiliating ways such as the once highly respected and highly powerful religious leader Jimmy Swaggart proclaiming, “I have sinned” while weeping profusely and begging forgiveness. The more pathological Ones attempt to suppress unwanted emotions or the more they turn their anger inward, the more they sink into depression. The more they preach abstinence, the more they overindulge in alcohol or drug abuse.
According to The Wisdom of the Enneagram, a pathological One on a downward slide is dogmatic and inflexible. She constantly rationalizes her own bad behavior. She becomes increasingly depressed, obsessive, compulsive, anxious, and self-destructive. She judges herself and others harshly, often flying into rages over perceived slights or missteps.
When they are losing their battle to maintain self-control, pathological Ones walk a daily tightrope between obsession and compulsion. Many eventually fail themselves, and their moral code, by performing a spontaneous, rebellious, truly unsavory physical act that breaches all of their rules. This means they become the ultimate hypocrite, for example, a priest who molests children, a minister caught with a prostitute, or a leader who betrays a nation.
Because they feel compelled to be pure and virtuous, Ones often develop obsessions with cleanliness or purging, becoming anorexics, bulimics, or so compulsive about cleansing they overuse laxatives or enemas. They can also become that obsessive-compulsive housewife who compulsively scrubs every inch of her floors, cabinets, and walls, especially the darkest corners, either to keep so busy she isn't thinking those nasty thoughts or to wash away the sins inherent in everyday life.
Disintegrating Ones become dangerous when they project their unacceptable thoughts, feelings, or behaviors onto others, making someone or something else the source of all their — and the entire world's — problems. When the rules, philosophy, or religion they use to order their world has failed to contain their impulses, disintegrated Ones can become dangerously vindictive and cruel. They vehemently believe they are absolutely right, have justice on their side, and are so pure it's virtually their duty to clean up the world. Once they project all the sins of the world onto a person or a group, they feel justified to show no mercy and offer no reprieves in what they see as their noble quest to annihilate the infidels. If you are involved in an intimate relationship with a pathological One, you can become the enemy and the victim of his or her distortion, regardless of whether you've done anything whatsoever to warrant it.
