Despite Dark Souls's reputation for being ball-crushingly difficult yet fair in its approach to kicking your ass over and over again, it doesn't always follow its own rules on what constitutes a fair game. It's not a stretch to say that over 95% of Dark Souls' boss fights are fair in the sense that you're given ample room to avoid getting beaten to a pulp and some breathing room to learn enemy attack patterns, but the Capra Demon ignores all of those established rules; he's a cheap douche-puppet who just doesn't care about fairness. Why it's unfair: "Oh look, there's a Fog Gate, I better prep myself for a boss fight. I'll go through and keep my distance so I can learn his... oh, I'm dead." That's your first encounter with the Capra Demon summed up perfectly. The second you push your way through the thick fog barrier, the Capra Demon will be all over you, ready to mount you like a dog in heat. And if he doesn't, his pet mutts will. Literally. There's nothing enjoyable about fighting the Capra Demon. His arena is barely the size of a cupboard, he has pet dogs that distract you, and he has a ridiculously large reach with his dual swords. Once you've beaten him for completionist's sake, there's zero reason to back and fight Capra again. Hell, he's not even a required kill to reach the end credits.
