I think that, in episodes like "The Crystal Cave" and "The Drawing of the Dark" it was made obvious that the future cannot be taken for granted. I'm pretty sure that if Merlin did not fracture Morgana's head, she would never be able to figure out Uther's secret and try to kill him. Gaius himself said that the crystals are treacherous. Merlin tried to change the future he saw, but he caused it himself.

Indeed, destiny talks become really philosophical. In my opinion, this subject should have been handled with more care by the show. I think that, if they took care of the Aithusa being the light of the sun issue better, as well as Mordred and Morgana's destiny after Merlin's intervention, everything would be more clear now!
