I am mind-boggled at the world of unseen. The jinns are able see the angels etc. Are the jins born pure and good like humans? How do they become followers of evil Shaitan of trying to bring down the children of Adam given that they are in the world of unseen and can interact with angels and other Muslim jinns. Are there any narratives of our Imams regarding this?

The jinns are tried like humans are tried. Allah has given them the intellect to know right from wrong. As Surah al-Jinn tells us, there are righteous jinns and evil jinns. The evil jinns chose to be evil. They were not created evil, nor were they forced to be evil. We call the evil jinns “shaytaans.” Iblis is the leader of the evil jinns. They follow him. But not all jinns follow him. There are good jinns.
