Alduin was supposed to wait for the time to destroy world. Sooner or later the world would have to end, Akatosh the only one who can decide it. His first born son Alduin was supposed to fulfil that purpose when the time came. However, in the first place, Alduin said screw all that, I will pretend that I am father and have foolish man worship me as the chief god. Then after his "worshipers" used elder scroll on him, he came back pissed. He decided, now you really made me mad, this world is getting destroyed, weather father likes it or not. So his father sent Dragonborn to deal with Alduin and put him back to his place. After that incident, Akatosh probably took Alduin home to put him in time out, until the time comes for the world to be destroyed. Then Akatosh would unleash Alduin on that world.
