This is very beautiful, and very chilling. I am sad for a Severus who finds himself such a haven and then has to renounce it so completely.

Rose of the West sent me a link to this on Saturday and I tried to review then but it had an open link I forgot to remove. After I clicked the submit button i was unable to get on TTP until a few minutes ago.

Depending on the context and the application Abraxas's and Dolohov's lessons could be taught to either side. To put it in context for the other side very little of the wording would need to be changed, it just depends on what your view of 'the greater good is. As human beings with human nature the people of the Wizarding World are all essentially the same, what they become is up to context and application. Severus is proof of that, he was able to change the whole context of how he viewed his world when he joined Dumbledore and became a spy and still use the applications he was taught against the dark side for the side of the light. The way he learned to dissociate as a child saved his life many times until Rowling decided he had to die. 

Anyway, Rose and I discussed how the story brings to mind to us the song 'Tomorrow Belongs to Me' from 'Cabaret'. I'll skip the link and just say the video is on YouTube.

'Tomorrow Belongs to Me' is probably the most seductive song I know. It starts out so sweet and gentle and the lilting melody wins you over. Even the lyrics are rather innocuous when you read them, but as it's performed in the film and in the stage productions I've seen of 'Cabaret' it ends up being the most chilling anthem I've ever heard and it's done so insidiously you hardly realize it because you are already swaying to the melody. It really could be the Pureblood Youth anthem.

I love this, and I'm going to favorite it, too.  I love the pastoral beginning that slowly becomes more and more sinister, but by the time you realize it you're way too far down the garden path to recover.  It's like the song "Tomorrow Belongs to Me" from Caberet.  I love that the one student who gives all the right answers is the one who's going to betray them all.  I love the history and detail you've put in here.  Thank you for pointing it out to me.
