They only started to notice you when you broke a shadow orb. Knowing that something was amiss, they sent their scouts to investigate, until they spotted a camp of indeterminate size containing indeterminate amounts of people.
They decided to launch an assault, but it ended horribly for them. All they wanted was balance, since your very presence meant that the island would soon turn into a wellspring of misfortune. And they were right. The guides had their life forces tied to the demons within hell, and as their lifeforces faded away, within dolls of demonic origin, a gigantic vertical mass of flesh with eyes and a set of teeth emerged from the fiery depths of Hell's lava lakes. Soon after that, you manage to kill the demon, and subsequently release all of the ancient spirits' souls, sending the forces of light to reform the land once more, and the forces of darkness to enhance their hold on reality.
Nothing was ever the same. The goblins got slaughtered slowly, but surely, until they were separated from each other. They only had one person to blame for all the misfortune they experienced. It was you. You who unsealed the ancient cruel spirits of the world. You who singlehandedly and heartlessly murdered all of the goblins heading your way. You who unwittingly destroyed the balance of the world, the balance that the goblins tried to maintain.
And then, they launch one last attack before they fade away from existence. Unfortunately for them, you climbed the ladder ever higher, even physically becoming a man who can go toe-to-toe with demigods. They were vanquished quickly, more than ever, until they were no more.
And you didn't even care. You only cared to reach the top of the ladder and become stronger and stronger...
What the hell, Hero?
