After a long, painful, impoverished life full of every kind of torment, many people thought they could finally rest in peace.
But with the advances in medicine, even the last scraps of a poor soul's remaining value would be squeezed dry. When a whale died, its enormous body became food for countless marine creatures; likewise, a person's death attracted many "decomposers." According to people's beautiful wishes, donors would hear things like how their lives continued on in others. But not all of these people were angelic sweethearts determined to give back to society when they grew up.
Sitting at the same table as Werewolves felt disgusting. The sight of them "feeding" was revolting and bloody, with none of the "aesthetic beauty" of Avada Kedavra. After Sirius Black was struck by the curse, he looked as though he had merely fallen asleep. From a certain perspective, it was a very aristocratic way to die.
When Cleopatra knew Octavian could never forgive her, the last female pharaoh of Egypt ended her life with cobra venom.
In Egyptian civilization, cobras represented the sacred, the opposite of the serpent in the Bible that tempted Adam and Eve into stealing the forbidden fruit.
Christianity in the Middle Ages regarded women as the source of temptation and suppressed them as if they were snakes, demanding that they be obedient, devout, and produce offspring as plentifully as cows. Humans only needed cows to keep getting pregnant and producing milk. They had no need for bull calves, so those were slaughtered for meat not long after they were born.
Women did not give birth just so their children could become "bull calves." When they lacked the ability to "foresee," they could obediently bear children and become mothers. But once they possessed that ability, they were unwilling to gamble.
