What if what the bible says about you is true and that blackest darkness is reserved for you forever? Jude 1:13.
I don't see any mentioning of psychopaths anywhere in the bible. The concept of psychopathy is new and came with the era of Psychology. In the past we were more likely to be called anything from warlords, leaders, politicians, artists, and everything that signifies unusual people who are unafraid of going beyond the limits of common norms... all that which is known to be needed in such people. - That is not to say that we weren't also known as infamous pirates or evil rulers, etc.
But psychopaths was not what we were called, for that term didn't exist then, it came in very recent time along with the new "ruling order" where the standard is set by the masses, the common and the mediocre. I do not mean to degrade people by saying this, I know that most common people in their hearts wouldn't want a common or average person as president or to be in any of the most important positions of leadership. Why I think a psychopath could fill such a position is a different matter which stems from my observation that there are different kinds of psychopaths and that many of those who wreck havoc today could've been something quite different had circumstances been different also.
But to answer your question more directly: Knowing that I might be send to the blackest darkness forever wouldn't change anything for me. It wouldn't change how I feel or how I behave anymore than I already am changing these, and I am changing these only within the boundaries of being what I am because I cannot change my neurological wiring.
And part of the consequence of my neurological wiring, which is my condition called psychopathy, means I do not believe I'm evil. I may understand on an intellectual level that according to a certain ideological construct I am evil in the eyes of those who have adopted said ideology on an emotional and moral level, adopted it as part of their identity and how they see themselves as well as how they understand good and evil. But since I can't adopt such an ideology, it can only be an intellectual theory to me. In my own mind I will always be convinced that I am as good as I can possibly be under the given circumstances. Some professionals call it rationalizing and failure to take responsibility, but to me it is the truth.
Furthermore, it isn't because I am defiant, I just can't feel afraid of something that is so far away in time and thought, a mental image. I have never seen nor heard any living human being describe the Blackest Darkness of the Bible. And therefore this idea is too unreal for me for it to trigger in me any emotional response in the form of fear or concern. I only feel curiosity. Curiosity as to why you and others would believe or even wish such a thing to be true, and curiosity as to how such a scenery came into being in the first place, and to the awareness that some people hate me so much that they will think of such an idea. There's no anger, no scorn, and definitely no fear or guilt.
I guess I believe it is possible that such a location exists, and therefore someone can experience being confined to that place for a period - maybe they can even experience being there for what to them seems like eternity, but I don't think it happens to just everyone who did something bad or wrong in life. With this I am touching on the difficult subject of subjective reality and how the individual can influence this. In fact, if I was to communicate more explicitly what I think and believe about this subject, I would have to discuss religious and magical practice throughout the existence of man. It is not that I don't want to do that, but it is a subject that goes beyond the scopes of psychopathy as such, and it would take a lot of text as well.
Perhaps I will discuss it in the future.
