I am a very very lazy person. I like to pride myself on being in the running with Lebowski. And to me hate takes way way to much energy. Having even the simple idea of killing has to take some effort. Kind of seems like he just set out on a life not worth living IMO
Ingrained racist beliefs, as well as a pragmatic ‘those are a group that can’t fight back if pushed against. I will blame them because I want the majority on my side.’
However one cannot overstate the role cultural antisemitism played. Hitler didn’t ‘one day wake up.’ Europe has had a long history of hating the jewish people. Scapegoating and Persicuting them. Blood liable for example was an accusation that popped up from time to time. Kidnapping people to mix their blood with matzah bread. Complete bunk, but the jewish people are a stateless people who do not share local traditions and norms nor do they worship at the same place. Plus they often found work doing the things that people either couldn’t or wouldn’t do, which lead to oft conspiricies of jewish money lenders puppeting from the background.
That is the sort of enviroment young Adolf grew up in. Same as how people in the modern US are essentially being taught to think of disadvantaged blacks and mexicans as a existenital threat sucking wealth away from them.
Respectfully, do some reading of even middleschool level history books. He didn’t personally decide to “be mean” to particular groups. His worldview was shaped by the post WWI dynamics in Europe, latent stereotypes and domestic problems within Germany, and a whole lot of misapplied emerging science. He literally believed in racial supremecy and was trying to build an ethnostate. This motivated him to define groups of ethnic “undesirables” and also to lump in other groups that he found politically inconvenient. Read about the scapegoating of Jews circa that time. He likely believed his cruelty towards them was somehow justified because he laid all of Germany’s problems (economic issues, humiliation of the country and loss of territory post-WWI) at their feet.
TL; DR - Bad actors believe their evil behavior is justified.
Scapegoating minorities was a tool for him to use to get into power, given that most people in Germany distrusted Jewish people at the time and coming off of the great war with massive dept and a broken country, someone would’ve taken advantage of the situation.
IIRC during the third Crusade, the Christians slaughtered 60,000 Jewish people before they even got out of Germany. The beef goes way back.
Some people will say the origin is Christ’s death. But even reading that story it’s clear that Europeans and Israelites weren’t on good terms then either.
It’s hard to find a “cause” for a belief that isn’t rational.
Pogroms were common throughout Europe for hundreds of years. Because Christians were forbidden from lending money at interest Jews were the ones doing the banking.
When a ruler got too far into debt they’d incite some religious hatred and miraculously be out of debt, because their creditors were dead or missing.
“Expelling the Jews” is a mechanic in Crusader Kings 2. And it gets abused like it did historically, too- borrow a shitload of money and then expel the Jews. Suddenly you found free money.
Is this a feature in CK3?
I don’t know. I have played very little CK3.
