Victor-Must-Kill Coupling Break
If lethal defeat means the same wizard must both defeat and kill the master, the Tower splits credit: Draco defeats but spares; Snape kills but never defeats. Dumbledore thus dies without a qualifying successor, fulfilling his aim to die “undefeated” by any single wizard and leaving the Elder Wand dormant or ownerless. Voldemort’s murder of Snape then accomplishes nothing; Snape never held allegiance. The finale loses the loyalty backfire that saves Harry; Voldemort wields a powerful but unbond
- DH: Dumbledore tells Draco he intended to die without truly being defeated by him.
- DH: Draco disarms (defeat) and Snape kills (lethal) are split events.
- General wandlore: wands track defeat; this interpretation demands unified defeat-and-kill.
- Theme: Dumbledore attempts to close the Elder Wand’s chain by avoiding a clean transfer.
