Friends are great. Which is why having friends is often what separates the hero from the villain. An inevitable side-effect of The Power of Friendship is if you don't have friends, there's something wrong with you. Similarly, if a writer is going to create a sympathetic Anti-Hero, they often choose to make the character a brooding loner. Although there are many other ways to make a flawed character--Pride, addiction, and lust are all sympathetic, epic flaws. No, no, instead, writers opt for just plain asocial. And, as Freaks proved, loners may be freaks, but freaks aren't loners.
