Here’s the rally at the end of the second movie where he shows those visions
Grindelwald is the Hitler analog who is trying to enslave humanity. But he’s the one trying to prevent the Holocaust. It’s insane.
I found a YouTube link in your comment. Here are links to the same video on alternative frontends that protect your privacy:
Im going to guess that in the third one he goes too far in an uncharacteristic manner like what happens to a lot of these villains because even if he is ruthless there has to be some extra shit to convince the audience that the guy preventing the deadliest war in human history is the true villain. Even if he is using that for propaganda purposes and is megalomaniac… I mean shit… Its world war 2
IIRC Grindelwald kills a baby in the very first scene he’s in in the first movie, so that’s how they establish that he’s evil.
Its weird but notable that all of JKR’s work in the Potterverse since book seven came out has been about how changing the past is bad. The Cursed Child was all about how going back in time to save Cedric Diggory’s life would somehow cause Voldemort to win, and then there’s this trilogy which explains that the Wizards couldn’t prevent the Holocaust because some unexplained worse thing would have happened.
It’s like JKR saw that “how it should have ended” short where Snape uses the time turner to kill Voldemort with a gun and took it way too seriously.
