"I had a vision that a swarm of monsters will attack the village on my sixteenth birthday and everyone will die. Maybe it was just a dream, but please help me prevent it from becoming reality."
In a world of magic and monsters, is such a thing as a vision of the future really so absurd? They could have trained, they could have planned countermeasures, they could have evacuated the village ahead of time. It is profoundly selfish to place the full burden on himself alone.
Sigh.
