I would go with Mikhail Tal because of his devastating sacrifices
which grandmaster played the most aggressive chess?

Garry Kasparov wrote that, based upon Judit Polgar's games, "if to 'play like a girl' meant anything in chess, it would mean relentless aggression."
Players like Tal and Kasparov are known for their dynamic play and tactics, Fischer was known for technical play and as an endgame virtuoso, but I can't really recall any player being described as "aggressive" other than J.Polgar.

i second this

Today's great players are almost all essaying super sharp, aggressive lines. The aggression that Carlsen plays is usually seen after move 30, but players such as Ivanchuk, Nakamura, Jobava, and Ding Liren are all attacking right out of the opening.

Alekhine was more than a little aggressive, but wasn’t a GM because he died before the title was created.

You may want to look at the history of the title. And yes, Alekhine was considered a Grandmaster.
