I’m getting back into the game, so let’s go ahead and revive this thread. I need to visit the forum frequently to earn back Trust lvl 3, and answering worgen questions is just what I need to get pumped about worgen again.
I almost feel like I answered this one, perhaps on another post.
There’s a few ways you could look at this one. Hierarchy, or fear. In terms of hierarchy, worgen - including Genn and his pack - live in a pack culture (see Wolfheart), where the Alpha does have to scold his followers if they get out of line, much like Ralaar Fangfire does in Curse of the Worgen. In contrast, if you’re talking about attempting to attack or scold a random worgen that doesn’t consider you a leader, you’re like to be disapointed by the results. https://i.imgur.com/cAK5m3w.jpg
The second way to look at that question would be fear. Something interesting to note is that while the quest Escape from Silverbrook litterally yells “There’s lamp oil in the back - make use of it. The fiends hate fire!” and has you burn worgen, suggesting worgen hate fire. Yet even wild worgen packs had long since lit their territory with torches, and even a giant bonfire (Brightwood Grove, Duskwood), and lit their dens with torches (Dark Riders).
Good question. A few things contribute to why the worgen is resistant to undeath. First and foremost, this is proven in-game, then backed up by a CDev response, then backed up by lore (unlike some CDev claims).
Ingame
This immunity becomes relevant in the Silverpine Forest questline, when Sylvanas is attempting to slay humans and raise them as undead, but the worgen get to the Hillsbrad Refugees first, who willingly accept the curse rather than be raised as undead slaves.
" Lord Darius Crowley says: Drink my blood and be reborn as worgen, immune to the depravity of the Forsaken."

Community Developer Response
This is explained further in a CDev Response, saying
Not only are the Val’kyr less powerful than the Lich King when it comes to raising the undead, but the worgen curse also makes raising them into undeath far more difficult than it is for normal humans. The worgen curse has roots in both the Emerald Dream (through the wolf Ancient, Goldrinn) and the holy power of the goddess Elune. In addition, those worgen who imbibe the waters of Tal’doren—through the ritual they undergo to maintain balance between the worgen curse and their humanity—have a further resistance to the corruption of undeath.

Why
So we’re told worgen cannot be raised as Forsaken, and we’ve seen that to be true. We’re told the reason is because worgen are connected to Goldrinn and Elune. But why does that matter? Truth is, Life and Death are two directly opposing forces in the World of Warcraft universe. Because the worgen curse is so fundamentally connected to Life through two druidic dieties, minor forces of Death have no say, and it takes far more powerful Death magic (ie. the Lich King) to break that bond.

And that’s why we don’t have werewolf zombies.
