That's what makes it so tragic! Two Epics, destined to be together, yet whose mutual desire to rule as gods drove them to try and kill each other! It's like Romeo and Juliet all over again, but with psychopathy instead of teenage hormones and superpowers instead of Italy.
It would give quotes like "These violent delights have violent ends/ And in their triumph die, like fire and powder/ Which, as they kiss, consume" a whole new meaning.
