I had heard the name but not read anything of his before reading the poem which is a beacon of clarity compared to that intro I read yesterday where I could barely follow what he wants to convey, it's almost word salad in places.
but now I am thinking about it he did tell a lot of his story - he said that while he was a junkie he was pretty docile, all he really thought about was his next shot but when he went into recovery then it was like ripping off a bandaid and he was facing the demons it had covered. and that's when he got dangerous.
so yes. as my ex used to like saying - he never asked to be born. and he's right - we are all consequences of what has come before. but it's not an excuse for what he did, is it.
