[MCU] Thor kills Thanos at the end of Infinity War, how does everything after that play out now?

Instead of gloating, he aims "for the head" this time or the blow to the chest proves fatal.

Thanos dies, Earth wins. Nobody gets snapped. Gamora is irreversibly dead, Vision can be brought back with the Time Stone most likely. Strange probably also uses the Time Stone to undo some damage if needed, but probably prefers not to overdo it.

The bigger question is - what does Earth do with the Stones? That part is probably a lot more problematic, as we'd be getting political. Would Earth's governments want to keep them on the planet, or specifically off it? If they'd keep it, would the universal powers let them? A lot of tough choices here and moral grays to consider. Mind Stone would likely remain on Earth in Vision's care, and Time Stone in Strange's, but the rest are more problematic. Power Stone it would make sense to return to Xandar, if there's anything left of it, and Thor may want to keep the Reality Stone. Soul Stone back to Vormir?
