The _true_ power Voldemort knows not

I was thinking about "the power Voldemort knows not," and it occurred to me 
that the said power might well not be love, but _friendship._

Think about it.  In the Pensieve scenes where we see Young Tom Riddle in 
action, it's made fairly clear that he has no friends.  Even the gang of 
followers he has when quizzing Prof. Slughorn about Horcruces are 
_followers,_ not friends; Riddle plainly doesn't care about them.

Harry, OTOH, has friends and does understand friendship.  Right at the end 
of HBP, he's got some stupid idea about going off on his own, but I think 
his friends won't let him, and they'll demand to be included, just as 
Neville, Luna and Ginny did on the trip to the Ministry.

So my own theory about the power is that it's friendship.  Voldemort may 
well be full of love, albeit only for himself.  Friendship, OTOH, he's never 
experienced in his life, and that may be his downfall.
