Are werewolves in DnD always evil? I remember there was a good werewolf in BG and a werewolf companion, Cernd, in BG2. And Cernd was pretty good for a neutral aligned druid.
Werewolves are chaotic evil as monsters, but as actual characters they are not always evil. The monster manual talks about how an effort must be made to resist the bloodthirsty nature of the curse, and that even if you have someone who does resist the curse, they will go bloodthirsty on a full moon anyway.
The actual text:
Curse of Lycanthropy. A humanoid creature can be afflicted with the curse of lycanthropy after being wounded by a lycanthrope, or if one or both of its parents are lycanthropes. A remove curse spell can rid an afflicted lycanthrope of the curse, but a natural born lycanthrope can be freed of the curse only with a wish.
A lycanthrope can either resist its curse or embrace it. By resisting the curse, a lycanthrope retains its normal alignment and personality while in humanoid form. It lives its life as it always has, burying deep the bestial urges raging inside it. However, when the full moon rises, the curse becomes too strong to resist, transforming the individual into its beast form-or into a horrible hybrid form that combines animal and humanoid traits. When the moon wanes, the beast within can be controlled once again. Especially if the cursed creature is unaware of its condition, it might not remember the events of its transformation, though those memories often haunt a lycanthrope as bloody dreams.
Some individuals see little point in fighting the curse and accept what they are. With time and experience, they learn to master their shapechanging ability and can assume beast form or hybrid form at will. Most lycanthropes that embrace their bestial natures succumb to bloodlust, becoming evil, opportunistic creatures that prey on the weak.
Seems very dark urge-esqe when you look at that huh.
The manual also has a sidepanel about player characters as lycanthropes, and how the DM has to decide, based on whether or not the player resists their curse or not, to issue alignment changes, or even take control of the character until the curse is resolved.
Most DMs I've encountered don't approach a player character with vampirism or lycanthropy lightly. It requires a lot of communication between player and DM, with a high possibility of the character being removed from that player's control if they lean into their monstrous nature too much.
