Headscratchers / Pokémon Rusty

• In the series finale, instead of sending Rusty to the past to talk his past self into staying with his father's deli, why didn't Julian, the EV trainer, send himself back to the "How to Breed a Perfect Pokemon" episode, and talk his past self out of helping Rusty create the perfect Bidoof?
  • In Julian's own words, "Everything bad that has ever happened to anyone is Rusty's fault." While telling past Julian not to make Peanut Butter would solve the current crisis, it wouldn't change the fact that Rusty's callousness and stupidity causes immense amounts of pain and suffering to every person and pokemon he comes across. Stopping him before he could even get started would save a lot of lives even before the Bidocalypse.
• Peanut Butter's murder of Agatha is a perfect example of what befell the trainers that opposed him, even moreso during his world conquest. Since Peanut Butter wouldn't harm his fellow Pokémon, his obvious target would be the human trainers that enslaved them. However, what would Peanut Butter have done to the Pokémon who were genuinely loyal to their masters?
