QUOTE : The Carrows punish protesters with torture. The best Snape can do about it is divert detentions Hagrid rather than the Carrows, at least until Hagrid gets caught throwing a “Support Harry Potter” party. Hagrid manages to flee Hogwarts, suggesting that Snape may have obstructed attempts to take him into custody. (HP/DH, 442) For Snape, with his hypersensitive protective reactions, standing by while adults torture children requires the utmost in self-control. But he can’t betray his true sentiments or he will be killed and replaced by someone worse.
