I don't follow or watch Mr Beast videos, but from what I've seen, they are largely driven by a money fetish and as far as "creativity", it feels on par with the more boring "What would you rather" conversations I had in middle school.
Maybe he has unlocked the key to virality by vigorously analyzing data, but looking at his videos, at a glance, it seems to more be formulaic, predictable, and simply having an actual budget that sets it apart (if it is actually set apart, as I find it hard to tell how much of it is others copying his work versus hius work being unoriginal).
Personally, I think human behaviour is massively influenced by culture and that we have an individual moral responsibility to take actions that work in favour of having a healthy culture. And I see that individual moral responsibility as resting particularly on those who profit from culturally influential activities (and if Mr. Beast isn't "culturally influential", please can we retire the term "influencer"). I see arguments often made that amount to justifying amoral, or even actively immoral, behaviours by the fact that money can be made from them, with an implicit assumption that humans have no free will when it comes to money, that an action that makes money has to be carried out and that this somehow morally absolves the one who does it. I see that as a corrosive meme and evidence of a deeply unhealthy culture, not as a conclusion that follows from adopting capitalism as the primary organising principle in a society.
Just a question of degree of nastiness? Yes, competitions involving life and death are qualitatively different from competitions involving money. Something interesting to think about is that we do have ultra graphic action movies and horror movies. Are those also net negative?

There is no human culture that I know of that was not fascinated by things like money and fame.

I don't think Mr Beast is immoral and not for the reasons you state. I think you have in your mind some very judgemental ideas of what is right and wrong.
I think shows like Mr Beast and all celebrity culture is dumb. I think sports are dumb too. I don't think they are evil and I know that humanity will find a way to create variants of these things no matter what kind of insane rules society tried to put in place.
