Why does Kilgarah deserve to die Merlaa? Deserves to die for having forgiven her? How does that make sense?

All he's ever done is advised Merlin right. Aithusa prolonged chaos in Albion, it saved Morgana's life! There's no way Aithusa is strong enough to beat Kilgarah, even when he's ill. I don't think he will kill Aithusa, but death is a suitable punishment. Besides, in the legends, the Red Dragon does kill the White one.
