The women Martin Place gunman Man Haron Monis was accused of sexually abusing feel "bewildered" by his death and "robbed" of their chance to get justice.
Several of his victims are being given support and counselling having been left "traumatised and fragile" after seeing the events unfold on Tuesday.
A source close to the supporting of the group of five women said they had felt they were making some progress having seen Monis charged with the offences but now realise he will never have to answer for his actions.
"There is a feeling of bewilderment," the source said.
"They are asking 'How the hell did we end up here in this nightmare? They are angry but really they don't know what they are angry about."
Monis was arrested by detectives from the sex crimes squad in April and charged with the indecent and sexual assault of a woman in western Sydney in 2002.
Police alleged Monis was a self-proclaimed "spiritual healer" who was an expert in black magic and astrology and operated out of a premises on Station Street, Wentworthville.
The woman who claims she was assaulted allegedly saw an advertisement for "Spiritual Consultation" in a community newspaper and contacted Monis who advised her to visit his clinic.
The woman visited the clinic twice within a week. On the first occasion it was to be alleged that Monis indecently assaulted the woman, who was 27 at the time.
Then, during a court appearance at Penrith in October, he was charged with the additional offences, including 22 counts of aggravated sexual assault and 14 counts of aggravated indecent assault relating to six other women.
Monis, who was on bail, was next due to appear in court in relation to indecent and sexual assault charges on February, 2015.
The source close to the five women said the charging of an offender often meant the start of the healing process for victims.
"Suddenly, that is not going to go any further," she said.
"Even though he is dead, some of them feel robbed. They wanted to see the offender to do every long hard day in jail. Now they aren't going to get that satisfaction."
The source said that the victims were women between the ages of 31 and 40.
She added: "All the victims had gone to him for spiritual guidance.
She alleged his "modus operandi" was to convince them, and obviously he was quite good at it, that he was the solution to their problems.
"Some of these women are fighting this alone because their families don't know and their siblings don't know because they have been too embarrassed to tell them," the source said.
