The trouble with S.P.E.W. is that Hermione wants it all and wants it now. Political movements take time as well as effort, so the notion of changing the world overnight is quite naive. Even when people are well-meaning, there’s always the risk of doing more harm than good.

Hermione’s methods might be ill-advised, but this doesn’t render her entire cause unworthy. Just because most elves don’t want freedom doesn’t mean they don’t deserve better treatment. Hermione’s dream of an elf in government might be far-fetched, but there’s merit in wanting to protect the vulnerable and allow them more choices. However, she ought to be careful – ‘tricking’ elves into freedom is arguably as unethical as enslavement.

Before we go, let’s consider Kreacher. Think of how he changed when treated with kindness by his new master, Harry Potter. Previously he’d been bitter and unpleasant, not to mention a liability to his previous owner. Had Sirius treated him a little better, things might have worked out differently. Dumbledore was right – being kind to Kreacher was in everyone’s best interests.

If you look at other translations, “SPEW” is often changed to that language’s word for “vomit,” “fart,” or “snot.”

The idea that Dobby is mentally unwell for wanting to be free has some upsetting historical precedent.
