For What It's Worth

'I always aimed to please But I nearly died' was a big revelation for the protagonist and hence a turning point in his life.

This is the first step into realizing he needs to change his approach to achieve what he wants.

But the song is not about taking better actions through that revelation because the protagonist is still reflecting on what led to this revelation.

At first, he wants to distract himself ('Come on lay with me 'cause I'm on fire') and he tries it one more time the old way ('I'd tear the sun in three to light up your eyes') showing once again how much he's prepared to do for his love, but ultimately he reflects on the things he's already done for her ('Broke up the family').

He understands that she's his 'disease' and he understands the position he's in now 'No one cares when you're down in the gutter'. So it's clear he's not ready to change yet. All this talk about 'For what it's worth' is like him saying 'What does it matter what I'm doing. I've fallen so low anyway. Can also make the best of it.'

This refers to ignoring the call to change and just having sex with her again by following his sexual desires ('Fill the cavity. Your God-shaped hole tonight').

The resolution of the song is that he's hit rock bottom. He's in the gutter and he's lost her too - the one person he gave up everything for. And that's a cautionary tale: If you lose yourself in order to be with someone and reject and push away everyone and everything else, then one day you'll end up completely alone and with nothing.

But when you look back at the first verse, the protagonist said: 'I always aimed to please but I nearly died'. This refers back to the ending of the song. The protagonist had been in the gutter but he made it through. He nearly died there. And now he can act as a mentor for other people who might be caught in the same situation.
