proof

issue: the list of all toppings is finite, but you included the 1st, 2nd, and so on best toppings. With no specified endpoint.

Thus Steve contains every topping, even the gnarly nasty ones. I will admit that you added each topping, but better, but how exactly can each of these toppings be any better than very bad?

• Glass
  
• Sand
  
• Cyanide
  
• Aerosol propellant
  
• Nintendo Switch cartridges
  
• Deodorant gel
  
• Pure, untreated Sulfur
  
• Neon green acryllic paint
  
• A wet lollipop covered in hair
  
• A really, really bad sandwich
  

Another problem: Steve can conceivably contain itself, and any sandwiches of infinite tastiness can conceivably contain themselves. Is there then a perfect sandwich that only contains toppings of itself, and, is it possible to create such a sandwich in the physical realm? If my hypothesis of "no" is correct, then why is life so cruel?
