Not really. While je does have a well defined morality and azrong sense of ju stice, he is also very egocentric and brash. Just to illustrate my point, look at some of his actions, like blowing up his aunt, and ask: if this was mass effect wast that a paragon or renegade choice?
Would that it were so simple.
Too much of an irritable jerkass in a fair few scenes to be an Ideal Hero.

The fact he's a fallible human being and not some paragon after all is at least part of the point of the character in the first place. He's The Chosen One who beat Voldemort (except really, that was Lily) and is destined to (maybe) do it again, but only because he's got a very powerful, very smart chessmaster pulling all sorts of strings to make it so. But whilst by no means is he a bad person, he is impulsive, stubborn and does have a few anger management issues occasionally, which does rule him out of both statuses to my mind.

You know, there is a perfectly fine Harry Potter thread to discuss this sort of thing.
Hey, it was only once, and it was an accident!

It's a trope, not a troop.
And yes, this belongs in the main Harry Potter thread. Hollering for a lock.

Can Harry Potter be called a Ideal Hero or The Paragon?
