Are these symptoms of a sociopath?

no you seem to have covered all the symptoms- My psychologist said that sociopaths are far more present than imagined about 10 per cent of the normal population and 90 percent of the prison population - They are mostly in top managerial jobs where their skills can be used. I am sorry that you neither understand have nor want empathy - Its great - I must say that I'd give you a very wide berth if we met.
