What would lead someone to practice satanism?

So, not sure what's up with my ex. We have years without been in contact.

Weeks ago I decided to look her up online. I found a profile pic of her.

*A sad selfie as profile pic

*Username: Satan

It makes me think. The username could mean anything, but then, what would even lean her to use "Satan" as username? If she really is into satanism, what made her go that way? For real, thats either a crazy ass 360° change, or she hid it from me all the time.🤷
