HRC/BC:
"A key difference between a psychopath and a sociopath is whether he has a conscience, the little voice inside that lets us know when we’re doing something wrong"
HRC:
"A psychopath doesn’t have a conscience. If he lies to you so he can steal your money, he won’t feel any moral qualms, though he may pretend to. He may observe others and then act the way they do so he’s not “found out,” Tompkins says."
BC:
"A sociopath typically has a conscience, but it’s weak. He may know that taking your money is wrong, and he might feel some guilt or remorse, but that won’t stop his behavior."
