1. Kindness corrupts: good deeds lead to bad consequences.
2. The player spreads the parasite while trying to help others.
More specifically:
You work in healthcare. Early in the morning, you receive a call from your boss about delivering humanitarian aid with essential items to people in his settlement. At the time, the disease was spreading.
Each time the protagonist delivered humanitarian aid, they spread the parasite and the disease further. With each passing day, their condition worsened: visual illusions, hallucinations, ringing in their ears, and whispers that speak to them within them. On the penultimate day, the protagonist's condition worsened and they began seeing all sorts of nonsense, including bloody footprints, trees, corpses, eyes in the sky, and bloodied villagers.
By the end of the game, the player can't cope and simply passes away.
