Lack of empathy is usually when one is a sociopath not suffering from schizophrenia or autism.
The problem is some people on the autism or schizophrenia spectrums cannot express themselves, but they have empathy and compassion, but are misunderstood by society and the news media. They just lack social skills and people skills, but can be taught them by books and therapy. Most are even nonviolent and very good people if only they were understood.
Sort of like Sherlock Holmes, only Doctor Watson seemed to be able to understand him, everyone else misunderstood him and didn't want anything to do with him because they thought he was a mean jerk with no empathy. He had empathy but got rid of distractions to focus on solving crimes to save humanity from evils like Professor Moriarty and his gangs of sociopaths.
I always see people using 'sociopath' as different from 'psycopath', and I also see people claim they mean the same thing, and I also see people say that neither are used anymore, technically speaking (as in psychiatrists). Anyone with formal training on the area would be kind to briefly (or not) clear this up?
