i have a follow up question to the harry potter theory that you added to: i'm sure a bunch of other people made the 'ultimate' sacrifice to try and save loved ones from voldemort so why didn't their love work the same way as lilly's? i'm 100% sure she wasn't the first mother to use herself as a shield against him
This explanation might be a bit long, but it’ll be worth it. First let’s get some facts out.
The most efficient way to kill someone with magic is the Killing Curse, which is forbidden. Most wizards frown upon using it. The muggle equivalent I’d say would be committing manslaughter with a bazooka. Why a bazooka? Because they are harder to obtain-- stick with me on this.
The Killing Curse is difficult to nail down, even for a regular Dark Wizard. If you recall in The Goblet of Fire, when “Moody” is teaching the class about Unforgiveables, he blatantly states that they could ‘all point their wands at him, say the spell and he doubts he’d get more than a nosebleed’.
For Avada Kedavra to work effectively, the killing intent needs to be there and it needs to be strong. If either of these criteria are not met, then the curse is nowhere near as effective. You’d get maimed, perhaps, but you wouldn’t die unless the wizard casting it truly wants to kill you, passionately.
[Potter Fan]: “But Michi, SNAPE used the curse on Dumbledore! And he was on Dumbledore’s side the whole time!”
Excellent argument, Potter Fan. However I once again note the novels-- it is revealed in Deathly Hallows that Snape had to kill Dumbledore, who was already dying. Snape didn’t want him dead out of malicious intent, rather, he was pulling a Kevorkian-esque assisted suicide. He wanted Dumbledore dead to relieve him of his misery. He was already dying, after all. Snape had also made the Unbreakable Vow and we all know what happens if you break one of those.
Now that we have the Killing Curse info out of the way let’s move on.
The meat of this argument is that Lily’s sacrifice placed a protection charm around Harry of the most ancient sort. Why isn’t this a commonplace thing though?
Because the circumstances to activate this ancient magic are very specific and terribly important.
Plenty of mothers would die for their children, as we’ve seen in the series. Alice Longbottom, Molly Weasley, even Narcissa would die for her Draco. A mother’s love is ultimate. Honestly it’s difficult to comprehend unless you’ve been a mother yourself. Rowling captured it quite well because she feels it for her children.
While not every reader would find themselves familiar with the sensation, it’s depicted well enough to comprehend. Most mothers instinctively protect their children and would gladly put themselves in harms way to protect them [ie: NOT MY DAUGHTER, YOU BITCH].
Let me make it clear that I am not belittling other mother’s love for their children but I am pointing out that the circumstances in which Lily Evans died were exceptionally specific and rare.
Harry was an infant, barely a year old. His mother was in her early twenties. So we’ve got a young mother and a wee baby. Not only this but it’s written that she used herself as a human shield to protect Harry from Voldemort with no regard to her own life. She knew her husband was dead. He charged Voldemort with no wand. She knew she was going to die...
But least we forget, Lily Evans was the cleverest witch of her age. Perhaps she knew of the ancient magic and knew how to properly enact it. Whether this was through an incantation or certain circumstances, either way her sacrifice worked. Harry was protected [and subsequently made into a Horcrux, whoops] by her love.
There’s also the idea that Harry’s magic was not yet fully formed. Children’s magic is terribly unpredictable, so an infant’s would be more so. Perhaps the bundle of fresh and untapped magic within Harry influenced the situation.
So the facts we have are:
Harry was an infant - baby magic
Lily is clever -- possibly knew of how to activate this spell
She used herself as a living shield
Voldemort used the Killing Curse
These circumstances were rather specific-- from the individuals involved to the spell used to dispose of them. I feel that these factors influenced the ancient magic. Plenty of mothers died with their children during the reign of Voldemort [and Grindelwald, I’m sure] but how many died shielding their infant children from Dark Wizards? It’s a statistical rarity.
Perhaps this happened before-- but I don’t see it happening during the reign of Voldemort. Why kill children when you can take them in, mold them and have your worshipers raise them to see you as a god?
Kill the mudbloods sure, but their parents aren’t magical-- perhaps they couldn’t activate that type of protection.
Sorry if this all seemed long and roundabout. But essentially there are many factors that worked into the ancient magic being activated-- the spell used. the intended target, the witch it was used on and the circumstances in which it was cast.
