Qualia are the inside view of sensory data and reward signals.

Think about it from an evolutionary perspective:

Animals that step into a lava flow or forest fire don't reproduce. Eventually some evolve the ability to detect intense heat from a distance, and pain as soon as tissue destruction is imminent. They do not have nor need a general understanding of the dangers of heat, or even conscious awareness that they've stepped on a hot coal.

The pain signal compels them, but that is very low level machinery. It had to continue compelling beings that developed larger and more sophisticated brains that are capable of abstract thought and reasoning. Feeling pain is one of the lowest level parts of the brain telling the higher parts exactly what its going to do in terms that permit no disagreement.
