Your therapist should be able to help you with this, I hope you continue to seek a therapist, even consider a psychiatrist, before you go onto repeating this criminal behaviour.
Have you also considered changing professions? Maybe being a careworker right now is not for you and it may put more victims at risk.
I am sure if you stick with a therapist you be able to answer those questions you asked in time.

In giving advice seek to help, not please your friend
