She didn't provide a very convincing purpose of this cult other than "to do good" and this was a stock answer used a number of times.
She said she believed in this "Jackie" mind control creature.

Mr Balakrishnan convinced his followers to conform by inventing “Jackie” - a type of dangerous, mystical creature who could control minds, jurors heard.
"Jackie" stood for Jehovah, Allah, Christ, Krishna and Immortal Easwaran, and Mr Balakrishnan told one victim he had to beat her "otherwise Jackie would kill or torture her”.
She also implied that Balakrishnan had destructive power, but somehow maintained he was a bastion of virtue.
