At what age does sociopathy usually develop?

Sociopathy, often referred to as antisocial personality disorder (ASPD), typically develops in late adolescence to early adulthood, with symptoms usually becoming evident by the age of 15. However, early signs can appear in childhood, such as persistent patterns of behavioral issues, aggression, or deceitfulness. Diagnosis is generally made in individuals 18 years or older, as personality traits continue to evolve during adolescence.
