Metal music is cathartic the same way a movie, a videogame, a book or a theater performance are.

You experience intensity, highs and lows, tension and release. You expose yourself to a harsh emotional rollercoaster, to digging deep into one's psyche, and come out on the other end hopefully invigorated and refreshed.

If metal music inspires violence, so do the Odyssey, Star Wars, Othello and many many others.
