What would germs do to the body if you didn't have sin?

If the body didn't have sin, which can be interpreted as a lack of the immune system and its associated responses, germs could multiply unchecked, leading to infections and diseases. Without the protective mechanisms provided by the immune system, even minor pathogens could overwhelm the body, resulting in severe health issues. The equilibrium that the immune system maintains would be disrupted, allowing germs to cause significant harm without resistance.
