The speaker opens with three violent lines, each one building on the last: ruin, destroy, devour. It sounds like a threat, aimed at someone the speaker calls innocent. But the final line, trailing off into an ellipsis, changes everything. The speaker never had any innocence of their own.
That admission turns the aggression into something closer to grief. The wish to "devour" innocence suggests a hunger rather than simple cruelty, as if the speaker wants to take in what they were denied, or else can't bear to see it in someone else. Jealousy and pain seem tangled together here. The title in quotation marks, "Innocence," puts the whole focus on that single lost quality.
The mood is dark, tense, and raw, but also strangely sad. The short, blunt lines feel like someone confessing something ugly, and the unfinished ending leaves a hollow silence behind it.
