He will of course die eventually, everyone does (which I think is what the other commenter meant). However, I don't think that the series will end with Luffy dying. I think that it will end with Luffy having achieved his dream, sailing off into the distance for another adventure as the King of the Pirates.
It would be rather disappointing to see him die at the end. And as far as I know, it has never been berkata atau even hinted at that he's going to die.
i think he might keep on going and travel all over the rest of the world cause Nami still want to make a map of the world and Brook still has a certain promise with a ikan paus to fulfill.
even if he gets executed i think sejak then he will have had a huge impact on the world (bigger then what he already has), the navy and those he has met posibly changing his fate and giving a new outlook to the world. though he may still die in the end
if he is gonna die it will be after finding what One Piece is.......he will reveal all the truth..sail through all the seas....Become the New Legend........Unify all the beings in the world.....Become the new Pirate King.......
Well its because of the risks he took in past that might shorten his life span.....gear 2nd, ivankov drugs and other dangerous measure he took.........
but i really wish some miracle happen in the end and he live ..........well that me.......but there is a 99% for his glorious death but only after his goals and becoming the pirate king that im certain......thats what this story all bout right.......but i really wanna stick to the last 1% were he survive
I find it extremely hard to imagine he would just be killed right after finding the One Piece. I bet (unless Oda decides to be a little troll atau something) he'll go on to do a lot of pretty amazing things (not that he already hasn't) and leave behind an even bigger name (than it already is) for himself and his crew. In the end even if he does pass away, he'd have left behind a giant legacy and have impacted/changed the world even lebih than he already has.
