I've got a better reason... Watching it will only make you a worse person. And I don't mean in the sense it's morally wrong, but that the act of joining in the crowd cheering for suffering and death will inevitably chip away at your empathy
I doubt the primary reason is monetary, this is the kind of wannabe influencer bullshit the MAGA leaders love to put on. It's performative larper fascism. I'm sure someone will find a way to make a profit, but they're doing it for the sake of doing it. It just makes their nipples hard
But more importantly, hate is a poison. Exposure makes it just a little bit easier to stomach next time. It's feeding the wolf in you that lusts for hurting others
