Wait, did you just write for the "Betterment" of mankind? How is a werewolf going to help someone? They cannot control their animalistic rage. Even in human form they suffer from mental instabilities. While in werewolf form, you are no longer human. You will kill and you will hunt. If you try to lock yourself up somewhere while in werewolf form and wait until morning arrives, you will lose health. Werewolves are hated by villagers and the general population of people. They are not to be loved. THey are to be hunted. And it should be like that. Players that transform into werewolves should also have downsides to being a werewolf instead of perks.
You cannot be a werewolf in ES and only prey on animals. You will die. They need to kill humans or people to survive. And the werewolf is werewolf. Daggerfall has a werewolf like the brown on in Van Helsing and the Bloodmoon wereowlves are smaller, but equally bestial.

This.
Who cares about the Shaman? You can still do the main quest as a werewolf. Just wait until Hircine contacts you.
Werewolves in ES use claws and teeth only. They cannot use weapons at all.
It's an argument of free will vs. determinism. This game is all about free will. As the player, my good character should accidentally become a werewolf and not be forced to remove the curse to maintain his humanity. If I can only play a bad character as a werewolf, then the Elder Scrolls haven't offered me a true role playing experience.
Hollywood is behind the times. Wolves aren't monsters. Humans recognised their human qualities and turned them into Lycanthropes, or men who turned into wolves. It comes up in the classics somewhere, a tribe of men who turn into wolves at each full moon. Humans domesticated wolves, that couldn't have happened if they were all bloodthirsty monsters. It's only Christianity that turned them into Satan's minions, into an expression of insanity.
In literature, the werewolf is presented as an antagonist as a cautionary tale for us. The stories are still relevant to us today because it tells us "Don't give into your animalistic nature". The wolf in the story of little red riding hood was a symbol of some kind of rapist. The stories aren't relevant to us today because of some "don't go into the woods during a full moon because you'll be eaten by a human wolf" theme. The inclusion of werewolves in modern literature is slowly leaning more towards their original depiction in literature as a useful ally, as a sympathetic creature that the reader can identify with. Bethesda shouldn't hang back with the Hollywood depiction of them as only being monsters, because although that makes a good horror film, it makes a really bland, two dimensional character for the player in the game to play with.
How can a supernatural creature, presented as practically invincible, and with greater strength and speed than a normal person, possibly act for the benefit of mankind? I don't know. You're right, that is a completely stupid premise. Every single example from popular culture shows that increased speed and strength leads to the world conquering villain, the evil overlord for ever and ever and ever. Doesn't it?
Hircine is the Daedric Lord of the Hunt. In Bloodmoon, the game doesn't kill you if you choose to only hunt animalistic prey. It just takes away massive chunks of your health.
I'm not saying that Werewolves should be goodytwoshoes. But the player should be given the opportunity to choose their own destiny. If that means that they become a rather large dog rather than a fearsome slavering monster, that's fine. But I'd rather have the ability to play with the game mechanic rather than having to give up the perks of being a werewolf because of the cons. The cons of being a werewolf accepted by humanity would be that you are less powerful than other werewolves, and that other werewolves (as well as Hircine) think you are less than adequate. The cons of being a fearsome slavering monster would be that humanity hates you.
Incidentally, read the book Twelve by Jasper Kent. It deals with vampires, rather than werewolves. The vampires help out the Russians during the Napoleonic invasion, but then become an enemy of mankind. So the main character is forced to choose between his patriotic loyalty and his loyalty to humanity.
