Jonathan Majors Kang the Conqueror of Marvel Studios, one of the most dangerous men in the Multiverse, was damaged by Loki''s final variant He Who, which continues to prune the sacred timeline, to prevent further Kangs coming into existence.
Fans on r/MarvelStudios are debating whether Kang had to ensure that Thanos was successful in his journey of gathering all the Infinity Stones and execution the Snap, perhaps acting behind the scenes to direct events down this very specific course. This also ties in with Doctor Strange''s 14,000,605 futures and only one route to success.
According to reports, the only concern for Kang variants is that this essentially overrides all other moral concerns, meaning that to arrive to the point where He Who Remains is trapped at the end of time the Snap must have happened.
The same applies to every major event on the sacred timeline, with a user referring to Judge Renslayers'' remarks that everything in Infinity War and Endgame (including the time travel shenanigans) was expected to happen.
It''s unlikely that Kang directly intervened in any effort to assist Thanos, although timelines in which the Avengers succeeded in stopping him on Titan or in Wakanda were likely reduced to prevent Kangs from developing.
In his next appearance in Ant-Man and the Wasp: Quantumania on February 17, 2023, we should learn more.
