Just like Ted Bundy appeared as a handsome young man to his victims who would open their doors and willingly invite him in, so are there dark archetypes. These types of people work for the dark to varying levels and degrees. In some cases, their mission is not of God and the Light, but their mission is to destroy the Light.
This is not done overtly, but energetically. It is done subtly. There are some who have channels of darkness leading and funding all that they do. On the surface, they can appear to be nice people. They can be friendly, even seemingly helpful. They can be non churchgoers, and I've know some who were avid churchgoers. Like beauty, which can often only be skin deep, those are dark archetypes are committed to various levels of destruction.
When you are with a person like this, in life, what happens is that on a very subtle yet deep level, they work to destroy your soul and bring you into the dark with them. It isn't overnight, but over time, the soul is damaged. Manipulative energies often are part of the power they receive, and one may feel like they owe the person, that they must take care of them.
Very often these types of people will plant programs into someone so that they will never leave them. I knew a man who was married to such a woman. Because he never sought help, but was strong willed enough early into the marriage to break free, legally he was free of her. Because he did not get the spiritual help he needed, he still believed all the manipulative programs that were put into him, and bought her housing in an exclusive area of the city, thanks to all the dark programs that were put into him that he had to keep taking care of her.
This was a woman who was financially well off and could afford lavish clothing and vacations without his help. She later met yet another man that she energetically manipulated, and soon he, too, was wanting to buy her a home when she already had bought a new one herself. From what I know, he is still energetically manipulated into believing that he, too, must take care of her for the rest of her life. She threw energies into everyone, even her female friends, so that they would always help her, because they were now programmed that they somehow, "owed her." And with every day that they spent with her, their souls were becoming more and more enshrouded by the dark.
Perhaps the most common archetype is what one of my friends kiddingly refers to as a vacuum cleaner. She said that one of her ex's was one. Many men and women know they type: a partner who, instead of enlivening how you experience life, they instead seem to suck the life force out of you.
Often people married to these types rely on alcohol. With enough alcohol, usually a person can medicate themselves so they don't really comprehend what is going on energetically or spiritually. Like any of these types, once one recognizes what is being done to them, the ones who have felt their higher calling and who know how to listen will extricate themselves from these types of relationships before their souls are completely destroyed.
Still others will be doomed to failure as a result of their association with someone like this. It is even more sad, and tragic, when such a person is one of their parents, as the child will suffer much without realizing why they cannot seem to get their life together the way others do. Often in this situation, they will turn to the dark for relief, because they either scoff at the Light or those who can really help them, because their souls have already been damaged. In this case, intervention is needed.
I know of one person who instead chose the dark, and so he too, now is funded by the dark and has become successful, with little effort on his part. The converse is not necessarily true but for those who have been 'nailed' in this way, it often becomes the easier way out. Another person I know of has become a true adult child, unable to fend for himself and at age 51, still lives with his parents and is completely dependent on their income. One might call him a lost soul. As an Empath and a Seer, what I can tell you is that this man has been done to very badly by those who "work for the dark." Remember, these can be people who are nice to you, but their spiritual foundation is in another place.
So these energies may be subtle, but they are dark and very damaging. When they damage a soul enough, no amount of free will can save them. Only God can, through those who are Gifted to be able to do this type of liberation, who have spiritual authority and spiritual healing power. It is then a person's karma as to whether they can find this help. It will be a test of whether they, themselves, truly want the Light because all too often staying with the Dark is seductive because it is easier, and too often, a known way of life.
