Why is it evil?
I see no evil in this:
https://en.wikipedia.org/wiki/Devadasi
The
Chola empire encouraged the devadasi system, In Tamil they are known as Devar Adigalar, (Where in Devar means in Tamil as "God" and Adigalar means in Tamil as "Servants", Which is put together into one makes as "God's Servant"). Devadasi are Men and women were dedicated to temple & god's service. They developed the system of music and dance employed during temple festivals.
Inscriptions reveal that the 400 dancers, their gurus and orchestras, were maintained by the Brihadeesvarar temple, Thanjavur, with munificent grants, including the daily disbursement of oil, turmeric, betel leaves and nuts.

Nattuvanars were the male accompanists of the devadasi during her performance. They conducted the music orchestra while the devadasi performed her service. Inscriptions reveal that nattuvanars were used to teach the Chola princess Kuntavai a thousand years ago.

As the Chola empire expanded in wealth and size, they built more temples throughout their country. Soon other emperors started imitating the Chola empire and developed the system.

Indians follow and worship the current prostitutes and filth spread through the entire entertainment industry but they have problem with Devadasis. Btw, devadasis were not simply prostitutes.
