When one person controls the mind of another, we talk of manipulation. It ranges from a slight form of influence to a real act of domination. The aim is making the controlled person an extension of one’s own ego and plans. The manipulator leads his life recruiting people day after day to form a real army of subjects of his own will. There is no number limit to it. The aim is to annihilate whatever person of like level. This feature is considered a danger, since the manipulator sees anybody else solely as a potential enemy. That is why he accepts only those who subject themselves to his own will or those who are no harm at all. The rest must be conquered, or even eliminated or destroyed, if need be.
The only way to avoid manipulation is education.
from the dictionary: "doctoring, deception, artful and unfair alteration of truth by insidious means to one’s own advantage so as to serve one’s own purpose"
