I actually love that you mentioned that abandoning a pack member is looked down upon.
Are there like degrees to it? Like is abandoning an alpha wolf as bad as a gamma one? Or is like abandoning an omega like the worst thing a pack could do?
Each one has a different layer to it.
Omegas: they are so vulnerable without a pack that abandoning them is one of the most horrifying thing a pack of werewolf could do. It is almost taboo. If another pack found out about it, they would shun that pack, maybe rip it apart.
Deltas: can survive a bit alone and are resilient, but since their instincts are so strongly connected to the care of a pack, being packless makes them incredibly disoriented. Their instincts go crazy, to the point where they neglect themselves so much they will slowly waste away.
Gammas: Gammas are the type of werewolf that can survive the most alone, but even then it's a miserable existence. Because they have no pack ground that is a safe place to let go of their constant hypervigilance, they end up overwhelmed, exhausted and incredibly skittish. (Gamma MC has a very hard time feeling safe again)
Betas: it is very cruel to abandon Betas, because it means they are unwanted, and this is the worst heartbreak a Beta could experience. In fact, Betas die very quickly if left by a pack, because their strong sensitivity and emotional attunement to the pack gets severed and betrayed too deeply for them to survive in most cases.
Alpha: stray alphas are very rare, but very heartbreaking. If an Alpha itself is abandoned, it means they are rejected completely by the pack. And that makes Alphas go crazy. The lack of other werewolves drives Alphas insane. Stray Alphas are often hyperaggressive, and so lonely it hurts.
