The difference between sociopathy and psychopathy is generally held to just be based on the source of the disorder, sociopathy being mostly social causation and psychopathy being mostly hereditary causes. My guess is that you're using sociopathy to refer to antisocial personality disorder specifically, one contested definition.

If anything, based on David T. Lykken's ideas, the psychopath should feel pure apathy due to a disposition to cortical under-arousal.

Then again, this is all just a matter of conflicting theories, so whatever works for you is probably best for the art.

I'm just using the terms the way I've heard them used previously, where the psychopath is the giddy murderer and the sociopath is the emotionally dull one. It's probably wrong, since I'm not a psych major or anything.

Thank you for clearing that up, I'll make a note to include disclaimers about these from now on.
