If I were Harry, I would probably wait a bit until the emotional chaos (both inside Harry and inside McGonagall) lowers a bit before telling them “hrm, you know, I’m the one who killed the Death Eaters”. If I were to even speak about it at all.
Harry seems to want to setup Hermoine as the hero. Taking responsibility for it doesn’t help with that goal.
