Yes. Sociopaths can love with a selfish intensity that puts other love to shame. Their love is a devouring, consuming sort of love. When I love someone, I feel like I want to inhale them -- to literally suck out their soul. When I kiss someone, I try to do just that.
Love may be blind for empaths, but a sociopath sees your faults clearly and loves you still. The sociopath's piercing eyes are not only unsettling because of their unwavering constancy, but because the sociopath's eyes can pierce through to your very soul, leaving you naked before his gaze. The sociopath's ignorance or disinterest in social norms means that he will not see you as the world sees you but how you truly are. They're free of the rose-colored glasses empaths falling in "love" often wear. I imagine this ability would be particularly appealing to those whose role in society doesn't reflect their true worth: members of disfavored races or socioeconomic backgrounds, the too-smart-for-their-own-good crowd, the still-waters-run-deep.
Sociopaths have a genius for adoring. Their understanding of your wants and needs matched with their charm and flexible personality mean that they can and will literally become the man or woman of your dreams. In fact, when I love, my first step is to gather as much information as possible about every aspect of the person's life in order to more closely resemble their ideal mate.
The closest analog to a sociopath's love is probably the love of a child: intense, accepting, selfish. And finally, like a child, the sociopath will be extremely loyal. A sociopath will never put you above himself, but he will readily put you above all others.
