I couldn't say for sure as I don't know them. But some people like to find power, satisfy curiosities and things like that. It never leads to a good end though. Sincerely hope you stay completely away from it. It is very dangerous and can ruin lives.
Everyone has different beliefs :/ some depending their cultures and others get influenced by society ... Don't be a follower be a leader . Believe what you want to believe don't let anyone tell you hat I believe in
Your friends are an extension of ones self, look at your profile picture, not very redeeming is it? Ask yourself, are these MY core values? Only you can truly answer that question. I hope you find the answer soon. :I
Because they can. I wouldn't but maybe they are curious and would like to meet the other brothers of creations we are all gods children. Including demons. But that never helps because Satan is only an angel.
Why should it matter? So long as they aren't doing anything crazy (sacrificing animals, injuring people), it's perfectly fine. It's not okay to instantly cut them off if you're just going off stereotypes. Wait a month, either they'll do something that proves you shouldn't be friends with them, or they'll drop the religion.
