In law & order episode "disabled" why did Jill Scott's character abuse her quadriplegic sister?

Tsar Nicolas 2nd was the one who was stopping the antichrist from coming to power. Now, Jews took over churches; it's the end. Apocalypse started because of abortions and mark of the beast documents. Antichrist Jew Lenin legalized abortion in Soviet Union. Social Security Number (Name of the beast that the beast gives you instead of your baptism name) was legalized by antichrist Jew Roosevelt. Antichrist Pope Francis approves microchipping and gays. Antichrist Patriarch Kiril of Russia tells people to listen to the antichrist Commie Jew gov't. His KGB name is agent Mikhailov. He sold alcohol and cigarettes. Jewish KGB's agent Mikhailov (Kiril) helped Jews with ecumenism (one world religion under the antichrist Jews). Now, True Church is going catacomb as the Last True Patriarch Irenaios of Jerusalem blessed a few years ago. Holy Fire stopped when Irenaios was unlawfully removed. Imposter antichrist fake Patriarch of Jerusalem Theophilos 3rd is faking Holy Fire now. Antichrist Bill Gates wants to chip you using vaccines. Coronavirus is a scam; 5G kills people and gov't blames on it COVID-19; gov't will kill people with 5G in November and will blame it on COVID and will mandate vaccines. Chipped people will be influenced by computers to take plastic grey card World Passport with no name on it; but when they stretch their hands to get it, gov't clerk will press secret button to administer the unforgivable green triple six by isotope rays (according to last prophet Vyacheslav Krasheninnikov). How to escape mark of the beast? By hiding within a small group (10-15 people according to saints Gabriel Urgebadze and Seraphim of Sarov); Orthodoxy is the only true faith; you must hide in order to escape mark of the beast; forgive me.

I dimly recall the episode, but I found a detailed summary that says that Dr. Huang determined that Janice beat Cara with the soap in a sock--a common weapon in domestic abuse--because she resented her sister needing so much of her care and time and having the spotlight before her MS stole Cara's singing career. But there's more...

"Fin and Huang question Janice. She says she only hit Cara once or twice, and when Larue tries to silence her, she still wants to speak. She denies raping her sister and says he was not home when it happened. Fin asks for the details on her alibi and she gives it to him. Janice says she loves her sister and everyone knows how special she is. When Huang asks if Cara is more special than her, she gets an irritated tone and says she herself can’t sing, but now Cara can’t talk. Huang chides her for enjoying Cara’s pain, and she says it is nice to see her experience the real world for once, and where are all those people that adored her? Huang wonders if Cara pities Janice, but Janice says she has her son. When Huang comments that Damien cares deeply for Cara, she says she raised him right and she is his mother. Huang says maybe Damien love Cara more than her, and this agitates Janice, who argues back. When Huang says that her fear is that Damien would choose Cara over her, she makes a move to attack Huang and Fin restrains her."
