No but, their parent falling for a cult because they were going through a though time is actually very real horror content
(i would argue that religions that force you to only meet with people of the same religion are actually cults trying to push you towards cutting off your other relationships so that you're lonelier, more depressed and easier to control are also good irl horror content but that's not what this is about, i just find most monotheist religions scary and i wanted to talk about it because i'm scared for some of my friends)
