Why did stalin suffer from a sense of inferiority

Stalin suffered a sense of inferiority because he suffered severe scarring from a serious childhood disease. The scarring on his face was due to the disease of small pox that happened to him at the age of 7. He was also born with two adjoined toes in his left foot. His left arm also was a bit shorter than his right arm because of an accident that he suffered at the age of 12.
