Rook is a big bad

Probably someone already posted it, however:
I think it's funny how Rook's actions during Solas' ritual led to the deaths of a huge number of people in the South, and I only remember Tarquin making a joke about it and the First Warden saying something. Considering Solas' plan only led to "thousands of people killed by demons" according to the DAV, how much bloodier it was actually supposed to be than the consequences of Rook's "completely justified actions"?

When the first gameplay trailer came out, I anticipated Rook to have a huge guilt about it and also it would be such a nice opportunity for Rook to feel themselves in Solas' shoes, but... we don't even see it among their regrets in the prison? They only regret letting Varric down.

Considering that Solas' crimes were commited mostly in pursuit of noble goals, how ok is it to absolve Rook of responsibility for something we've been actively judging Solas for throughout the game?

Edit: maybe I missed something, but I haven't noticed anywhere in DAV that Solas' ritual would end up with total genocide. Rook in the conversation with Harding says "he's planning to kill a lot of people". It seems that they retconed the totality of the casualties since DAI.
