They somehow think that innocent people being free shows them as somehow being soft on crime, because it requires compassion which is clearly a weakness, or something they just don't experience, because they're a sociopath. There's a reason so many "successful" people show sociopathic and psychopathic tendencies, it lets them do things others aren't willing to do.
