What characters do you personally think are largely misinterpreted?

While I know that as a character he is seen from multiple perspectives, this is just mine, but I feel like some people misinterpreted Snape. A lot of people say he should belong in Gryffindor or how he is an example of a 'good' Slytherin (for a lack of a better way to say it, I love every house!).

I see no nobility in his actions, Snape is very arrogant and mean in the exact same way that James was only without growing up. Snape doesn't seem to progress from the teenager he was. This isn't a negative representation of J.K.'s writing but a positive, because it's something that I don't think a lot of people notice. He is often sneering down his nose at a majority of characters. If given the opportunity he would have, (and I believe this is true till the day he died), murdered Harry in cold blood if it meant the Lily would be back and truly love him.

Snape acts selfishly, his love for Lily is not pure, but a mangled obsession, crudely interpreted as love. My favourite example of this, as was mentioned on here, is his patronous, the exact replica of the doe rather than one which compliments it. As for keeping HP alive, I believe it's his obsession to keep that last bit of Lily around, which is reiterated as he is dying.

Hes only redemption comes with Draco who he seems to care for. But as I feel people misinterpret Draco as a 'somewhat badass guy who made the wrong choices but is good all along' when in fact he is a snivelling, cowardly git, I don't hold him highly for it.

It's not that I hate the bad guy because Voldemort is one of my favourite characters of any book. I just feel like people get to the end of the books and disregard everything that happened in the past, even when re reading.

It's really late so I don't think I explained myself very well, but I wanted to get the American's opinions as well.

EDIT: I just have to say this is why I love this subreddit. People feel passionate about the characters and defend/condemn them according to actual reasoning rather than an 'I like him so your wrong' mentality. This is one of the reasons I prefer books to films, films tend to limit perspectives because they have to for the sake of film, but with books you can have a million different views on the same character.
