Wicca is dangerous. Have had friends that were drawn into this. One quickly got out because God showed her that she was calling on demons to protect her and that her younger sister was watching her and considering following in her footsteps. So she called on God and her sister saw that and was spared from having to go through the pain and experimentation she went through.
With another pair of sisters, one followed her younger sister into wicca out of disillusion and disappointment with God and man, yet she had already wandered from God and into sin, unrepentant sin. Both have had nothing but broken relationships, pain and despair. Now that older sister is back in church, but we aren't close since she didn't want to keep in touch, yet sadly she has a lot of bitterness and anger with her Christian mother for remarrying so quickly after her father died. It was quick, within a year, and my theory is that the couple was seeking to honor God by marrying rather than living together and they both were near 60 and knew time was short given that they've both lost their spouses of 30+ years and found comfort in each other.
My point is that we don't live in a vacuum and that our choices affect others. People are watching all of us, being influenced for good or for ill and TV is called programming for a reason. I was really impressed by that first group of sisters since the older sister listened to God's warning for her, the revelation of the truth of what she was involved in and how she was making an impact on her own sister (maybe others, too!) and repented and returned to God. She was and still is a very impressive woman. She's over a decade younger than me and has awesome depth and maturity. She was one of many women who have been sexually abused. She had every right to be bitter and angry. She clung to God instead.
