The novel had no influence on Xun Can, Emperor Xian, his fellows, historians (ok did on some historians after novel published) who saw Xun Yu as a Han loyalist. The novel may have helped Xun Yu's placing among Han loyalists but the repuation was already there. Given Cao Cao likely ordered Xun Yu's death, I'm not sure it is a good sign he waited till after Xun Yu was forced to commit suicide, mere practically.
Xun Yu was a humble man but you may be overplaying that angle about Xun Yu
“You, are a rebellious son who abandoned his father. You are a cruel brigand who murdered his lord. How can Heaven and Earth put up with you for long? And unless you die soon, how can you face the sight of men?”
