Let's say that sometime after Fisk is put away, Matt decided he can't make the same mistake with Karen as he did with Foggy, so he told her about Daredevil. How differently do you think Daredevil season 2 would have gone if Karen learned Matt's secret identity at the very beginning of the season, rather than at the end? Would it have made the season end on a better note? A worse note? Would Karen would be much frustrated as Foggy is? When Elektra enters the picture? How would she react to Frank nearly killing Matt?
