What causes one to lose control? How do people lose track of each other? What causes rifts? Why are they frequent? What's wrong with cloning? Living two lives? Complications are never really a great thing. Sure, complications allow one to show strength and provide an avenue for growth, but are they worth it? One never knows until the end.
