I can respect that. But because he caused wars (Jedi Civil War) and intended on Genocide of the Sith Empire makes it wrong. The problem with loose cannons (which may be cool in the movies) is that they do what they want and don't care about consequences.
granted revan has gone thru alot i wouldnt call him a loose cannon yet. its just not characteristic of him but then again who knows wat goes on in his mind.
