Enlightenment is more than realizing absolute truth. Any uncharted territory in the body/mind, the being will translate that into Pain. Going into that Pain (the greatest opportunity), after that, the agony will translate into something very different. Pain is the greatest guide, why? Because the conscious mind did not explore the full body, due to social indoctrination.
As shown in movies, in a higher state of being there is no more "remorse". Meaning, one will become one with the Great Change we see all around. The pain people talk about is just a condition in the general mass, a mindset.
