Relation und Realität

something strikes me as odd, there is a peculiar similarity between Snape and Harry Potter: first it is their appearance, both are rather pale, have black hair (apart from the fact that Snape´s ist greasy and Harry´s is untidy). Then it´s their history, both had an unpleasent childhood (Harry reads in Snape´s mind, at one of their occlumency lessons, that Snape´s Parents had a quarrel, probably it was a longterm situation, at Hogwarths, Snape reminds an outsider, Harry himself suffered from the Dursley´s). Both have a mark, that connects them directly to Voldemort (Snape has the dark mark of the death-eaters, Harry the scar), at the same time, both are directly connected to Dumbledore. They share being torn between the Good and the Evil. At least, in The Order of the Phoenix, this similarity grows, due to the mode of description, Rowling uses on them. Harry´s behaviour suddenly resembles Snape´s, when Harry´s described as sarcastically, rising his eyebrowes, Harry snarles, or snorts, normally verbs depicted to Snape.

Is Snape kind of an alter-ego to Harry, someone, who Harry could have become, under certain circumstances? At least, it´s all up to decisions. Both Harry and Snape chose to get in their favourite Hogwarths-group, although the sorting hat proposed another one (what could it have been regarding Snape, Ravenclaw?)
