Percy question

Potterfanme has started a thread wondering if Percy will apologize.  
I have long thought, as all of you must have, that Percy's behavior 
in OoP is reprehensible.  But because his behavior was so extreme, 
I've been forced to wonder if Percy is indeed Percy, when he 
certainly isn't acting "himself."  The main thing that would 
contradict this notion is the prevalence of the the importance of 
choice in the series.
Any thoughts?
