fan theory: When a wild Pokémon faints it dies

Evidence/speculation nr1: In one of the first episodes of the series Ash’s pikachu faints, and ash tries to rush him to the poke-center, now that’s raised a lot of questions like, what would happen if he didn’t get there in time? Why don’t we have to rush fainted pokemon in any game? Well my theory is that when a Pokémon gets in a poke ball they get transformed into a code or anti-material, witch keeps them at the same exact status and form, they don’t get better our worse, and that’s why there’s no rush to heal a fainted pokemon. Now Ash knew that pika refused to get in the ball and that’s why he didn’t put him in the ball and decided to try to rush to the center instead. So if the pokemon doesn’t get in a ball our doesn’t get to a center in time, it dies.

Nr.2: Why can’t you catch a fainted Pokemon? That’s because no matter the status of the Pokemon, it always decides on its own to stay/get in the poke ball, so a Pokemon who is fainted can’t decide that. Now why is it easier to catch a hurt Pokemon? Because the Pokemon knows that if it has a poke ball, it will not die. So they try to fight back, but once they are low on health, they realize that if they faint then they will die so they make the decision to stay in the ball for its own survival.

If wild Pokemon dies if they faint how come tamed/caught not die eminently after they faint? That’s because they die slowly, like ash’s pika would if he didn’t get him too the center in time

(Remember this is only a stupid theory, no need to take it seriously)
