Bey is very much in the occult/black magic (I believe it was passed down generations within her mom's side. That's the vibe I get). Rih is in the occult too but she's more of a puppet than anything. She does everything she's told.
And when you think about all of these artists are vessels. Their life is really not there's. So in a way they did sacrifice themselves to be in the industry.
I've talked to a few ppl who've worked with some artists and they told me that the occult practice within the industry is very real.
But calling Li a sacrifice is stupid. Why would she be a sacrifice??

For WHAT?
Personally, I don't see why ppl make it such a big deal. They're probably the same ones who look up their horoscope every day tho.
