No, it is not normal to become a psychopath simply because someone becomes an atheist. There is no direct causation between a person's religious beliefs (or lack thereof) and their mental health or personality traits.
Being an atheist means someone does not believe in the existence of deities or gods. It does not dictate or determine a person's moral values or personality. Similarly, being religious or having faith in a particular belief system does not automatically make someone immune to mental health issues or guarantee good moral character.
Psychopathy, also known as Antisocial Personality Disorder (ASPD), is a complex mental health condition characterized by a lack of empathy, manipulative behavior, and a disregard for the rights and feelings of others. Psychopathy is believed to be influenced by a combination of genetic, neurological, and environmental factors, and it typically develops in early adulthood.
It's important not to equate religious or non-religious beliefs with mental health conditions. People from all belief backgrounds can have various mental health conditions or personality traits. Mental health issues are complex and can arise due to a combination of factors, including genetics, life experiences, and environmental influences.
If you or someone you know is experiencing mental health concerns, including symptoms associated with psychopathy or any other condition, it is essential to seek help from a qualified mental health professional. They can provide an accurate diagnosis and appropriate treatment options tailored to the individual's needs.
