*CAUTION - RANT AHEAD*
I do hope Sir Conan Doyle's intention was not to feel sympathy for this man, for I had none. Half of the story consists of his incessant whining about an undisclosed malady. Perhaps it was a glewiness, sizyness or otherwise viscidity in his bodily fluids. Maybe it was just something in the aether. We never find out, or if we did maybe it was at a point in which I stopped paying attention. Whatever the cause of his distress, it doesn't stop him from taking up spelunking and monster hunting as recreational pastimes.
When the monster is finally introduced, we see a lumbering giant of a beast that has the audacity to ignore the good doctor not once, but twice. Maybe that's what drives our protagonist into a killing rage. The monster doesn't even confront our hero until it has been fired upon and chased back into his/her home. Can you blame it, really?
Hardcastle later assumes that he was saved from a gruesome death because the bright light he was carrying. I'd rather like to think that the monster was just trying to slap the stupid out of him. There is only circumstantial evidence pointing his killing sheep and no recorded attacks on humans. If it was eating the sheep, what of it? Everyone likes him some tasty mutton.
So everyone gathers at the cave entrance, they have a blasting party, the end.
I'm not sure what I should be taking away from this. If something looks scary, it must be inherently evil? That it's ok to be an asshole when vacationing in small towns? I got nothing.
