He made that as a waful joke, to the point even his fans also asking him to stop making those edgy jokes. He used to make N-word or any edgy joke because he was toxic gamer mentality. I remember seeing a total backlash on Pewdiepie official subreddit.
After the incident, he stopped making any edgy jokes. All of his content in the past half decade are basically wholesome or hobbyist stuff. He also recognize his mistake on several occasion.
He's basically a classic trait of toxic gamer, making a racist remarks towards everyone. He was never a nazi in the first place.
Back when he did Hitler joke stuff, he instantly got backlash from his own community. He recognized the mistake and stopped doing it again.
I can assure you, these people are often doing it for banter or just for edginess. Never actually hates people.
I’m from SEA region, and people in SEA online gaming community did this all the time. Mocking each other ethnic groups or nationalities, while not actually hating each other, except for small minorities of course. Making Hitler joke, N-word, and other local edgy jokes.
Not saying this is a good thing.
Again, even his fans constantly asking him to do better all the time. And he’s now a better person.
I recommend to check his video about 100 days art journey: https://www.youtube.com/watch?v=MJDtQTTAogk It’s one of high-regarding art journey video that even contantly get shared and reacted among art community.
