Abysmal sports ethics by him.
Oh well, who cares, no one gonna remember him after he retires, just like no one talks about gerd muller or raul.
No way, Messi will be hailed as the goat, which means since he is always linked with him people will rank him top 5 at least.
If anything,they will forget the dives and his antics like they do currently with his play as long as he scores.
People will look at the results: performing in two leagues, all prices won, several ballon d'or's, amazing stats, a major contribution to the team awards and a comparison to the best player who he even bested at times (see ballon d'ors and stats after Messi 2012).
Its an extremely superficial way of looking at it, but thats the way the football world works, it is visable even today let alone when he is done.
OD you remember how many of his 23 hattricks were helped by penaldo dives? probably not but the hattrick stat ( and stats in general) will be remembered.
He cares greatly about his image/legacy and is working hard at it, a shitload of fans already worships him based on shallow perceptions.
As a purist, it pisses me off.
