What's the Marxist position on Psychopathy and "ontologically evil" people in general?

ontologicallly evil is just idealism per excellence. Psychology is also heavily based on capitalist base (as a superstructure) and often serves to "neutralify" and "make into nature" various conditions not conductive to productivity and exploitation. OG marxists even considered the entire field to be quack science in general. Not that I agree, but given how everyone and their mom nowadays uses clinical language/how psychology as a field is constructed as the factory line to fix labor alienation and the cognitive war against the individual waged by the empire. I can see why they doubted its usefulness.
