1. First of all, Voldemort knew there was such a prophecy, but he didn't fully understand it. Dumbledore was there when Sybil made this prediction, but there was an eavesdropper in the three brooms. He only heard the beginning, that is, he predicted that the boy's birthday would be in July, and his parents had defeated Voldemort three times. And in the third film, Sybil made a prediction and didn't know what he had done. It seems that going directly to Hogwarts to rob teachers is not a simple matter. Only the person mentioned in the prophecy can get the prophecy ball. This prediction is made for those who have the means to exchange all the contents. ("Ha 5")

2. speculation. In Ha 6, I learned that Slytherin's pendant is a horcrux. After memory confirmation and reasoning with Dumbledore to save money, I found the characteristics of horcruxes.

His mother is pure blood, but his father is muggle, and his real name is the same as his father, so he hates his real name. His mother is a descendant of Slytherin, so he is considered to be. Although his blood is not pure, Slytherin has always advocated pure blood. So is he. He despises Muggles, but wants to be strong, and "clean up" the magical world and rule the world in the way of Slytherin.
