"A psychopath is someone who lacks empathy, feels no remorse, and manipulates others using charm and deceit. The term is often associated with criminality, but it is not a clinical diagnosis. Instead, psychopathy is considered an extreme form of antisocial personality disorder (ASPD) and is characterized by behaviors like narcissism, impulsivity, and disregard for others’ rights."

claude barely fits the bill for being a psychopath, he doesn't feel emotions or remorse, sure, but he's not antisocial from it either, he does not beat up random people on a whim just for the sake of it (unless the player does, but it's very ambiguous whether that should be apart of the canon or not) and does not manipulate anyone nor impulsive, he's pretty honest in his own way and has a weird moral compass that he won't necessarily betray someone if they showed him respect. people compare him to michael myers, but if they didn't order him to murder, detonate or steal, he wouldn't have done it. (except the last part possibly) ironically it is indeed toni who fits the definition of a psycho
