With as many people as there are claiming that Wanda is a Nazi....
It's just occurred to me that these people are likely on the younger side, and might legitimately not have realized the significance of her stint with HYDRA.
So with that in mind...let's go into a little refresher on Doctor Mengele...
During World War II, Doctor Mengele was one of the Nazi scientists who experimented on Jewish victims who had been sent to the concentration camp at Auschwitz.
In particular, Mengele was known for his fascination with twins.
There’s a very good article HERE, which I’m going to be quoting from, but let’s look at some of the parallels between Dr. Strucker and Dr. Mengele that are hinted at in Wanda and Pietro’s “recruitment” in the MCU.
Mengele's handsome physical appearance, fastidious dress, and calm demeanor seemingly contradicted his attraction to murder and gruesome experiments.
His ability to elude capture increased his notoriety
Mengele would get very excited when he found twins. The other SS officers who helped unload the transports had been given special instructions to find twins, dwarfs, giants or anyone else with a unique hereditary trait like a club foot or heterochromia (each eye a different color) [...] The twins were then tattooed and given a number from a special sequence. They were then taken to the twins' barracks where they were required to fill out a form.
About 3,000 twins were pulled from the masses on the ramp, most of them children; only around 200 survived. When the twins were found, they were taken away from their parents.
Since they were "Mengele's children," they were treated differently than other prisoners.
Though they suffered through medical experiments, the twins were often allowed to keep their hair and allowed to keep their own clothes.
Mengele's presence did not necessarily cause fear in the children. He was often known to appear with pockets full of candy and chocolates, to pat them on the head, talk with them, and sometimes even play. Many of the children, especially the younger ones, called him "Uncle Mengele."
The twins were given brief instruction in makeshift "classes" and were sometimes even allowed to play soccer. The children were not required to do hard work and had jobs like being a messenger. Twins were also spared from punishments as well as from the frequent selections within the camp.
The twins had some of the best conditions at Auschwitz until the trucks came to take them to the experiments.
... the twins underwent various medical experiments. Mengele kept his exact reasoning for his experiments a secret. Many of the twins that he experimented on weren't sure for what purpose the individual experiments were for, or what exactly what was being injected or done to them.
The autopsies became the final experiment. [Dr. Miklos Nyiszli] performed autopsies on twins who had died from the experiments or who had been purposely killed just for after-death measurements and examination.
And, of course, there’s the whole “HYDRA is basically the Marvel Universe’s version of Nazis” thing to take into consideration.
It truly is a rather unsettling parallel when you look at it, especially given that the Maximoff twins are supposed to be from a Jewish family.
(And that it was Captain America who eventually rescued them, as a call back to Steve raiding prison camps in The First Avenger.)
