True enough. But then why does the modern Turkish state continue to deny what happened to the Ottoman Armenians? You think they'd have a field day showing how much the Empire sucked.
A government does not gain from showing its society a proper mirror. It runs the risk of losing ground by having "insulted" the guilty older generation and national identity, and simultaneously plants the distrust for itself (it mostly is that older generation) to form a youth revolt (the RAF supposedly formed from this distrust in West Germany.)
