Who has dual personality in the twelve constellations?

Scorpio. Scorpio's dual personality is that one is an angel and the other is a devil. When some Scorpio people look like angels, their hearts may be crazy, or when they are nice to you, they are actually planning a conspiracy in their hearts. Fortunately, their reason and calmness can control themselves. Otherwise, if their bellies are really black, their opponents will be miserable. Although they won't take the initiative to hurt others, as long as others offend him a little, he will haunt them until the revenge is over. It's really terrible!
