For Turkey to admit the Genocide is not a matter of not having the courage to say "sorry" but a matter of facing the consequences of their actions.
Consequences that imply repair to the victim's families and borders to Armenia. That is why the negation of the Genocide is so important for the Turks. To the point they'll jail their own scholars if they mention it.
I am a descendant of a survivor of the Genocide. My great-grandmother who died at 96 when I was ~10, told me, and I now 45, remember clearly, how all her children, but my yet unborn grandmother, were killed in front of her and her husband eyes. She could later escape disguised in a carriage of dead bodies.
