To me it seems like he wanted to avenge CSS and also saw an opportunity to get the archives. So he took it.
I cannot disagree with you, but i just wanted to believe he did it for css🤣 He killed two birds with one stone, not just punishing the 8 families, he also killed fifth princess's aides to shame the marquis yue (he mentions this while asking A'Qiu if everything was ready) but i do believe that he was very angry about what happened to css, and wanted to vent his anger.
