I know this is going to sound like some clickbait bullshit title, but I’m genuinely curious, asking in good faith. My two oldest sons are enamored with him, and he seems like a genuine guy, so I’m asking - is he a nice guy? If you google the question, you get a bunch of reddit hate, which I don’t always trust, because…it’s reddit. I have not watched much content (not my thing, I’m old) but I’m just curious what the fediverse has to say.
OP’s question was “Is Mr. Beast a good person?” and the answer to that is exceedingly gray and hard to pin down. He does a hell of a lot of philanthropy, but he does it by exploiting people. Do the ends justify the means? One could argue either way.
To the more narrow question that you’re posing, “Is he a good role model for OP’s sons?” the answer is HELL NO, HE EXPLOITS POOR PEOPLE.
