Why was the left handed twin so evil?

In many mythologies and stories, the left-handed twin often represents chaos, darkness, or the antithesis of the right-handed twin, who embodies order and goodness. This duality symbolizes the struggle between opposing forces within human nature. The left-handed twin's "evil" nature can be interpreted as a necessary counterpart to the right twin's virtues, highlighting the complexity of morality and the balance of good and evil in the world. Ultimately, their conflict illustrates the idea that both aspects are integral to existence.
