I am confused as to the connection between the Undead, eventually "lead" by Arthas, and demons and a few more. If you can answer any, I appreciate it.
1. Was Arthas always too ambitious that his reign would've led to something problematic? In other words: Did his association with horrible cursed items cause him to become a douche or was it something they just exacerbated something in the young man?
2. Culling of Strat - arguably a totally necessary action: right? As you plainly see going through the dungeon, the people ARE in fact infected. Not saying it's not cold. That doesn't make it the wrong move.
3. Why do the undead and demonic forces clash? Weren't they created by the same entity?
4. When did "Arthas Menethil" disappear? At Cull of Strat? When he took The Sword? When he took up The Helm? Did he ever actually stop inhabiting that creature his physical body had become? (I know, multiple answers.)
5. So lastly - and this is pretty deep into lore so bare with my mistakes and correct them: The "Plague of Undeath" is a magical affliction first conjured by Ner'zhul, the Lich King (under the direction of the demon lord Kil'jaeden)..." So the demonic forces created the Undead on Azeroth.
MILLION DOLLAR QUESTION: Exactly how are the Undead and demons affiliated? Are they enemies? Are they disappointed Grandmothers hoping you made more burgers for the party....sorry got personal there.
