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.
