God will only bring his house down after we fix the place up a little bit, WE must save ourselves this time.
It's not wrong to violently beat up a man in a ring for money if that money has agreed to it - I don't think it's ideal per say, so it will come with consequences and over time, if it isn't what God wants us doing, those consequences will become very costly. That's how all of this works - we can do whatever's we want but we will face the consequences and there will always be them, eventually we will learn that even tho we can do anything we want, we shouldn't, we should just follow that Greatest Commandment - that truly is the easiest thing to do.
Tbh if you think about it at all, the whole idea of mortal, unforgivable, hellfire worthy sin - it all falls down when you consider that God made this reality and is there y responsible for all that he allows to occur within it, the exact same way if I make a violent sexual game for kids, its my fault, not the children for playing it.
Thou shall not judge. BC we can't - we don't have any ideas what is worthy of judgement or not and we can't fr our current point of view.
