I'm writing a Backstory of Werewolves,
But there is a problem These Werewolves are not for Horror movies/novels.
Our Teacher in Literature/English wants us(me) to do a backstory for this one, I will make two of these, one for the school and one for a SP Backstory.

I need help to segregate the best and worst traits of a werewolf.
Advantages and Disadvantages/Pros & Cons
So I can Remove the Disadvantges/Cons to make them likable.

I mean we are not going for a Horror Movie/story type of Werewolves .
Long Question made short:
How can I make Werewolves likable or make them be the good guys rather than Monsters?
