Cover art for Cold Piece lyrics by Jerry Cantrell

Let it be, basically, im guessing. I like how he turns it around at the end. Instead of him its I. The first part w/ he i.e."He's not yours to save" may be coming from someone else. Then the author confirms what is said possibly sarcastically. I get the feeling this is saying "It's my life, if you don't approve that is fine, but let me be,.I'll live my life how i want.

Just a guess, if someone has a better idea I'd like to hear it, I'm open to interpretation.
