What would happen if one escaped Plato's Cave

In a discussion with his students, the famous philosopher was confronted with the question about reality. His response was that reality was like a cave. The cave he was describing had a fire in the very back of it with a few people casting shadows on the wall of the cave from the fire. Then closest to the wall there were prisoners who could only see the shadows cast on the wall. The prisoners only reality were the shadows cast upon the wall of the cave. Now imagine what if one of the prisoners managed to escape?

If a prisoner had escaped the cave he/she would see sunlight for the first time. They would be blinded by the light and be outside for the first time. They would then want to help everyone else in the cave see what reality really is. The ex prisoner would return to the cave and tell everyone that their whole reality is false. Now nobody in the cave would like to hear that everything they believe is completely wrong. So they would first deny what the escaped prisoner had said. But knowing truly what reality is the ex prisoner would persist in trying to get people to come outside. They would soon become angry at him and kill him. This is a perfect example on how people in real life for the past five thousand years have reacted to people that try to tell them their reality is wrong. Nobody likes being told that their whole belief system is false so they react harshly.
