That is VERY true.
Like, the High Council was planning on ripping the Universe apart back in the Sound of Drums.
What about the Nightmare child? The Army of Meanwhiles and Neverweres, led by the Could’ve been King? The Hoard of Travesties?
Like, damn. Some fucked up shit went down on the Time Lord side of the war. Yes, there were innocents. But burning Gallifrey was JUST AS MUCH about stopping the Time Lords as it was about stopping the Daleks. People forget that in Classic Who? The Time Lords were NEVER heroes. They were very often the antagonists to the renegade Doctor.
This episode glossed over all the interesting moral complexity that the Time War provided for a feel good ending.
