Xcyanx το πνεύμα του arthas δεν καταστράφηκε αλλά ενώθηκε με το πνεύμα του Ner'zhul σε βαθμό τελειότητας ώστε να δημιουργηθεί ο νέος lich king. Αν κοιτάξεις το cinematic που δείχνει τον θάνατο του θα δεις ότι στο τέλος νιώθει κάποια λύπη για ότι έκανε.
Να και τι λένε στο wowwiki για το θέμα:
Lich King - WoWWiki - Your guide to the World of Warcraft
When asked, "What's the truth about the new Lich King?", Chris Metzen replied: "Arthas and Ner'zhul have become a perfect fusion of one being - Arthas' personality and body with Ner'zhul's wisdom, experience, power and EVIL."
After peering into the Lich King's heart, Tirion Fordring remarks that "there's nothing left to redeem" and "there is no Arthas Menethil anymore - there is only the Lich King."

Before Arthas donned the Lich King's armor, it was the spirit of the former Orc Shaman Ner'zhul whose soul was attached to the armor and then imprisoned (physically) inside the Frozen Throne. Now Arthas and Ner'zhul's spirit are one and together they are the Lich King.
In a dream state where Arthas sees past, present, and future, presented by Ner'zhul, Arthas murders the child manifestation of his humanity (e.g. love, compassion, and so forth). Delighted at this decision Ner'zhul states "We are one, Arthas. Together we are the Lich King. No more Ner'zhul, no more Arthas -- only this one glorious being." With that Arthas murders Ner'zhul and tells him "No we. No one tells me what to do. I've got everything I need from you -- now the power is mine and mine alone. Now there is only I. I am the Lich King. And I am ready." Ner'zhul is stunned by the betrayal, then disappears.
[4] It is uncertain if this dream state actually results in Arthas murdering Ner'zhul's essence, but it would seem to indicate that Arthas's soul lords over Ner'zhul's.
A new question arose when Frostmourne was shattered and Arthas died. In his final moments, Arthas seemed to display a humane remorse for his atrocities while allied with the Scourge. This signifies that his spirit was released when the Lich King was defeated.
