They demand worship and absolute loyalty. They are always right and you must conform to their ideas and wishes in order to be around them. A truly evil person is one who steals hope . They paint bleak and horrible scenarios of life and then portray themselves as the only persons with any answers. They allow for no other vision.
Evil always wants control and power over others.
It feels no remorse for stealing the hopes and dreams of others to gain that control. Each of us does deal with evil persons just about everyday. Remember evil comes in degrees. It grows and increasingly controls the individual who succumbs to it. Ordinary sinners who do not allow the Spirit of God to transform their thinking can become evil.
