"I would like to ask you something we know that a lot of killers and serial killers became newborn in prison my question is can psychopath or sociopath get interested in bible before committing crime? or he just does it in prison as an act? can he truly believe in whats written there?Thank you."Psychopaths have their individual beliefs as all other people do. They differ not so much in the question about whether they believe in a god/religion, but more in that they tend to not care if they follow the scriptures and words of the god they believe to exist.
I myself believe there are many gods. Allah, Christ, Jahweh, Satan, or the many gods of various Pantheons, are all real in my understanding. But I don't adhere to any of their teachings even though I was brought up with the Christian faith, as most Westerners are.
Again: Basically the question of belief is one that only the individual person - psychopath or non-psychopath - can decide for themselves.
But I will say this: Most of those who become what you call 'newborn' (Born Again Christian) in prison - if they're psychopaths, anyway - generally don't do so because they suddenly have had a revelation and now believe in Christ when before they didn't, they're doing it because they hope it may influence heir case in a positive direction. You can't start believing in something like you press a button to open a program, it has to come from within and must start somewhere unrelated to mere self interest. So if you didn't believe in Christ before you killed or before you were caught and sentenced, there isn't much chance that you will believe afterwards.
To your question about whether a psychopath would become interested in the bible before committing a crime, the answer is much the same. If he is already a believer, he might want to consult the bible before engaging in crime, especially something that is considered very serious by the Christian faith. But if he has no relationship with religion at all, there isn't much chance he would suddenly want to read the bible while preparing for a crime. Rather, he'd be interested in learning as much as he can about the crime and how to get away with it - unless he's acting on impulse or in a fit of anger, in which cases he won't be likely to think twice about what he's about to do.
