Loki Disney Plus - Trailer

If he did we wouldn't be getting Kang in Ant-Man. If you think about it, there was still a multiverse, it's just that the same important things all happened in them and whenever something different happens, that's when it creates a branch that he then prunes. Kid Loki was fine until he killed Thor. Alligator Loki was fine until he ate the wrong neighbor's pet.(God bless him)
I don’t think that follows
Sylvie just killed the Kang that kept all other Kangs in check (probably by killing them then pruning new Kang timelines)
Now Kangs will run amok again
