Sunshine

@kachimbo11 I think you nailed it with your interpretation. I agree with most but will add just a couple items.

Full of sick desire - either: he wishes so hard that his mother was back that it's affecting his life in general, he himself said he doesn't know how to function now that his mother is gone. OR - Conversely, this loss has caused him to run to a life of excess as a way of trying to cover up and blunt his feelings and emotions over her death (much like people "pour themselves into their work"). This lifestyle has allowed him to give in to debauched excesses that most would perhaps consider him to be "full of sick desire," i.e., the worse (for him), the better. He may feel so inconsolable and lost, but he "don't mind...I don't care no more." He's so numb at this point, that he feels numb to the awful things he's now doing. See, Jerry acts like a badass mofo rocker, but deep down, I don't think that's really who he is. I think he just went there because at that point in his life he had nothing else. Layne scooped him up when he was at his lowest point, and the rocked the world together. And when the opportunity for said debauchery presented itself, he grabbed it with both hands, even though it might not actually have been something he would have gravitated toward.

Am I that I promise? - I think this is based on his promise to his mother to become famous, make money, buy her a house so that she'd never have to work another day in her life (which she had to do to keep the 4 of them all afloat). But now that she's gone, he is unable to fulfill his promise to her, and he feels guilty about that.

Am I worth the value? - this may be Jerry asking himself if he's worth living at this point, what's the use, everyone he loves has died. He's living this weird lifestyle that he likes, but at the same time he feels kind of guilty about it, because many people might look down upon it, so he wonders if he's even worth being around anymore.

Do my love defile? - Wondering if he'll follow the same path as his father when it comes to women - doing hurtful things to them, breaking their hearts, leaving them behind, acting uncaring. Again, I think Jerry WANTS a long term relationship, but his lifestyle (in his own words) as turned him into a "wolf" where he just goes in for the kill, and then moves on.

Memory, set me free - I think he's reverting back to his memories with his mother because that's when his life was happy, peaceful, and carefree. The memories he had from then take him away from this new world of pain, uncertainty and death.

I don't care no more - he's numb, emotionless, doesn't really care one way or another what happens to him.

Is my soul entire? - he feels as if his soul has been ripped out of him, or broken in pieces. He can't seem to reconcile continuing through his life feeling the way he does, broken.

I've always had a heart for Jerry - he gets deserted by his father, loses the 2 people closest to him at a young age, then gets rescued by the most amazing person he's ever met, only to watch said rescuer die a long, slow, agonizing, self-inflicted death, crushing all of Jerry's dreams and goals in the process, forcing Jerry to do things he never wanted to do, and go forward with a limping band of friends that's never been the same since the rescuer died. WHAT a life he's had.
