Question re Chapter 13 - The Secret Riddle

[mgrantwich]

Harry and Dumbledore go pensieve-diving into Dumbledore's memory of 
meeting the 11-year-old Tom Riddle at the orphanage and telling him 
the news about going to Hogwarts.  Dumbledore is obviously disturbed 
at Tom's (probably regretted later once he'd got over the shock) 
comments that he can control and/or hurt people and animals if he 
wants to.  

Given Dumbledore's concern, wasn't it just a bit...off-message, shall 
we say....to respond to Tom's request for a magic demonstration by 
torching his wardrobe in a display of intimidating power?  Not to 
mention just a little OOC for Dumbledore?

What would a clearly disturbed and ammoral 11-year-old take from such 
a performance?
