Looking at the countries currently trying to replace the US none of them are better. Russia an Iran are pretty obvious. China is already working hard on enslaving the poorest countries in the world. For most of the rest the US Empire falling apart, just means local dictators continue their rule.
Add to that the violence of the conflicts and I gurantee you very few will celebrate that collapse.
China is currently debt trapping most of Africa. They pretty much appointed the current dictator of Zimbawe for example.
The way I look at good and bad is on a scale. Whenever a country makes the life for the average human better in terms of material well being, but also political freedom, that is a good thing. Whenever they make those things worse then it is bad.
A huge reason the US is the country doing so many bad things, is that nearly nobody else can. Any large scale war between two countries in recent times had the US being the agressor or the US intervening massivly. Iraq was done after invading Kuwait and Russia despute having nukes and a resilient economy is not liking it either.
So we have to look at what countries choose to do with the power they have and the US is not the worst in that metric.
