The Key to Snape?

I'm not going to pretend that I have done anywhere near the level
of assessment of Snape's character that many on the list have done.
Heck, I'm not even sure whether Snape is Evil!Snape or Good!Snape
or Selfish!Snape or some combination thereof.

But one thing I have a very strong hunch about is that the key to
understanding Snape is contained in the "Snape's Worst Memory"
chapter of OP.  Namely, why was that his worst memory?  What
element of that incident is the one so horrific to Snape that he
considers it his worst memory?

I can't shake the feeling that when we know for certain the answer
to that question, we'll be able to determine which Snape is the
Real!Snape.  And since I shouldn't really make that assertion
without throwing in a theory, here's my theory...  ;-)

I think it's his worst memory because he called Lily a Mudblood.
