Sorry you are in that situation. It must be brutally hard on you from a psychological angle, so I think your feelings are totally understandable.

I think societies have a right to defend themselves from those who either from psychological illness or ill-will or a combination of both, either cannot or will not control their antisocial actions.

It would be nice if being in a correctional facility led a person infallibly toward a whole new direction in life and freedom from their antisocial desires.

Sadly, that ideal is not always realized. Often confinement in a correctional facility can cause a person to a have a greater desire to reoffend and a greater desire to "get even" with society that they blame for their ills.

Perhaps I am wrong about this and perhaps I am wrong about what I am now going to say, but I think it is wise to steer clear of this individual you mention, not only for your physical health but also for your psychological health.

If you happen to be a religious person you might pray for this individual and for his victims and possible future victims.

On how to get over someone, I am at a loss. The brain seems to have a mind of its own and does not always mesh with what we would like it to do. I believe that there are psychological techniques for getting over someone. Some I think are available for free on the Internet.

Why some people become sociopaths is still pretty much of a mystery to the current level of knowledge of modern psychology although progress has been made in this area.

I try to stick to that old adage: "hate the sin, but love the sinner." although this is much easier said than done. Perhaps I am too naive.

All the factors in a lifetime of minutes and seconds that go into creating a type of personality is something only a Divine Being could know.

Humans can know little about a person in comparison. We certainly don't see clearly the trillions of things that have led a person to a certain point in their life: genetics, environment, upbringing and so on.

We are denied the omniscience to see clearly what is ill-will and malice and what are other factors and weight of each in leading to a personality.

If I were you [and I am not in your shoes and so cannot advise] I think I would steer clear of this individual.

When my brain takes to me places I don't want it to lead to me I try to transmute that content into a prayer so that something beautiful can come out of something ugly. Sometimes beautiful flowers emerge from soil covered in dung.

A lot of modern psychology is the creation of atheists, agnostics and such and I am sure they have a wealth of knowledge concerning very helpful techniques for dealing with things that don't involve prayer.

There are many books on how to get over someone or some awful experience. Many can be gotten for free or a small fee from public libraries in countries that have public libraries. I read some many decades ago but my memory fails me on the content.

I feel sad for the victims of this individual. How tragic and heartbreaking what they must have gone through. Just unimaginable pain and anguish that may last their entire lives.

I hope pray they will be freed from the after effects of their terrible, terrible trauma and that some how , someway they can get some peace of mind or joy of living again.

Profound apologies for not know exactly how to be helpful to you. It is so hard to know how to be helpful rather than unhelpful or hurtful sometimes.

I am sorry you are suffering. I would be too I think. I wish I knew how to take the pain away. I hope others here will have better words for you than my poor, poor words. You deserve the best! You are a nice person and so helpful to others here on the Forums.
