Will Usopp or Luffy get an incurable disease?

[Warmmedown]

Chopper gotta fulfil his dream of curing every disease, so is that gonna be when Usopp actually gets a disease like the ones he always fibs about or is it going to be when Luffa gets Roger's incurable disease or gets ill from using the gears?

 

[Captain Cadaver]

If they do, I find it far more likely Law will use the immortal surgery to counteract it and sacrifice himself. Considering how little shine Chopper's had for years, I doubt his dream of curing all diseases will be fully realised, at least in a satisfying way.

Maybe, although they could just use Law to create suspense or a bit more unpredictability.

So you don't believe every SH will have their dream fulfilled?
