Some canon Shen Jiu facts and implied information
- no he didn't try to kill Liu Qingge when they were disciples and Liu Qingge jumped to conclusions
- yes he did ambush Liu Qingge frequently and unprovoked and loudly threatened to kill him in public for the sin of having talent and a positive home life
- yes Liu Qingge barged in on him when he was in the brothel
- no it wasn't unprovoked. Shen Jiu had beat the everloving shit out of his Shidi
- Said Shidi had made nasty remarks to Shen Jiu at the door of the brothel. Probably bad ones but no not good enough to justify almost beating a man to death
- implied he went to the brothel only to sleep
- heavily implied by Shang Qinghua that Shen Jiu was a virgin when he died in SVSSS
- no he didn't kill Liu Qingge in the caves but even he's like "I kinda get the allegations tbh"
- Shen Jiu did murder people pretty casually when he was a rogue cultivator including innocent people who did not deserve it
- He also abused the shit out of Luo Binghe for the sin of having potential and having once been loved. He strung up a child and whipped him bloody. This cannot be excused and indeed he doesn't make excuses for it
- unconfirmed if he had done this to others
- probable but unconfirmed that he gave Luo Binghe the fake cultivation manual. He specifically hated that Luo Binghe had potential and wanted to ruin it. [EDIT: @bayesiandragon reminded me that Shen Jiu is confirmed in canon that he did give Luo Binghe a fake manual. So that is canon. I knew I was right but couldn't remember it stated so couldn't back it up so all thanks to Bayesiandragon for that]
- he probably didn't have sexual intentions towards Ning Yingying BUT there is a good chance he did something to make her feel uncomfortable and unsafe. She sided with Luo Binghe in the end and Shen Jiu is a curious type of man hating misogynist and he is also very possessive over what he thinks of as his. I think he was more along the lines of a possessive parent who infantilised Ning Yingying and made her ultimately uncomfortable and unhappy. That is a headcanon but it's reasonable to suggest that in some way Ning Yingying was not having a good time by the time Bing-ge showed back up from the Abyss. Evidence is that SVSSS is allowed to mature in a way that PIDW Ning Yingying was not
- not knowing why Yue Qingyuan didn't show up did hurt him deeply but wasn't what doomed him. His belief that he was an irredeemable monster from birth because he would have preferred Yue Qi die then for him to become Yue Qingyuan, was what doomed him
- he is pitiful little mess of a man but he's also an abusive fuckhead these are both true
- he does not want to change and isn't willing to
