Pearl Jam - Alive Lyrics Meaning

To start this interpretation you really should begin with Eddie's life..
Eddie's mother was married to his biological father but they split up when he was just a young baby. She remarried another man and Eddie grew up thinking that he was the father. Being a mother concerned for her child's innocence, she didn't tell Eddie the truth. But one day she confessed that the man Eddie thought was his father was actually not and that Eddie's real father, a man he always thought to be just an old family friend, was actually his father and that he had died years before.
Eddie took these parts of his life and created a story (It's actually in 3 parts)..
This part is the story of a kid who, much like Vedder, found out that the man he thought was his father wasn't and that his real dad had died years before. His mother was stricken with guilt and began to see the biological father's face in her son so she began a sexual relation (possible abuse) with her son. The "I'm still alive" part isn't happy and a 'yeah! I'm gonna make it just fine!' tribute line it's actually a curse that's filled with guilt.
The other 2 parts are apparently about how the man grows up to become a serial killer who eventually is sent to death row and executed.
This is the story I've always know.
