What is the Grinch?

What are his origins? He seems anatomically similar to the Whos of Whoville, just with green skin with an abnormal amount of body hair. Is he a mutated Who who was born like that or is his disfigurement a result of some childhood accident?

One must remember that in 'Who' society the highest virtue is conformity. While they are a generally peaceful and friendly people they produce few great artists and innovators, this is in part because their whole culture is focused on the good of the community above the individual. One could attribute this to their snowbound environment, where for much of their history any deviant behaviour could be disastrous for teh community, and this has carried on into modern times. 

Now imagine a child. Mother is no-one of great import, father is unknown. Born with oddly distorted features and green skin. He goes to school, the teachers do their best to be polite but they are always a little hesitant with him. The children are less kind. He grows up with no friends, and always feels isolated in the communal events that form such a large part of Who-ish society, the most important of which is their ritual exchange of gifts at Christmas of course. 

As he grows older he begins to spend more time in the wilderness, safe from the looks of the crowds. First as a woodsman, but eventually moving there permanently and establishing his own life away from the community. He brings his beloved dog Max, the only living creature that has ever shown him kindness. 

Over time he becomes more isolated, more bitter and resentful of the community that would not accept him. Then at the moment of their greatest festival, in the depths of winter, something inside him snaps....
