Woman sacrificed her life for Beyonce.

A 23-year-old American woman known as Taniya Hattersfield committed suicide in sacrifice to the singer Beyonce who she considered her "lord and saviour". She was a new member of the National Church of Bey(In this church they worship Beyonce). 

Taniya's body was found in the basement of her family home, College Park, Georgia, surrounded by a self-made shrine dedicated to the star.
This caused rage among people who are urging Beyonce to speak against Beyism, but no reaction yet.
Do we call this stupidity or lunacy?
