Probably, but the Kang in Ant-Man said that he was the most powerful of all of them, so now that he was easily killed, what interest should we have to watch everything if the other Kangs will be easier to kill?
Marvel just dropped the ball so hard. If Kang is dead, they negate his power and menace. If he is alive, then there’s no consequences for anything and like usual, death means nothing, and can’t take it seriously.
Whoever wrote and greenlit the ending of Ant-Man, just destroyed Phase 5 in the first movie. There could still be other good movies and whatnot, but it’s going to be very hard to take this villain seriously and be invested in him.
