Jesus Christ, where to begin? Amazing essay and great subject matter. To add my two cents I'll say the following:
All (i think it's safe to generalize this) great artists/thinkers are tortured souls, Hemingway, Vangoh, Dali, Frida, Trotsky, etc. were tortured in one way or another or some tragic event, like in the case of Frida Kalo, was/is the source of their thoughts and work. The way they decide to deal with their problems is through their work until they are so miserable they kill themselves (Hemingway was also an alchoholic).
There is no doubt in my mind that Steve is tortured by something and expresses it through his works whether conciously or subconciously. All Writing teachers say the same thing, "write about what you know," usually your experiances and yourself. Bruce wrote about fencing... his hobby, so Stever writing about his fears and dreams is not so far fetched.
Thus I must conclude that from syl's rant it is not difficult to say that Steve is a great artists that expresses his vision and handles his inner demons rather well through his music.
