In the chapter where Draco beat around the bush at the beginning of the sixth book, Harry followed Draco to Bojinbok's shop in knockturn Hutong. At that time, he rolled up his sleeves and showed his arm to Mr. Bojinbo. When he was shocked, Mr. Bojinbo immediately respected him, which was the beginning of Harry's suspicion that he had become a death eater.

However, Voldemort turned him into a death eater, not because Voldemort valued him, but to punish the Malfoy family. Because of his poor performance in the final battle of the fifth Ministry of Magic and his failure to protect Voldemort's diary, Draco was given an almost impossible task: to kill Dumbledore and let Lucius watch his son fail. However, due to Deng's organ failure, Draco succeeded, so little Malfoy was saved.

In the seventh part, Draco is basically in a state of contradiction. It can be seen that he can't accept the cruelty of death eaters. Their family was snubbed by Voldemort, and Lucius was eager to make some contributions to save his position. Well, that's beside the point. . )
