I have a character delivering a monologue (fortunately not too long), and want to capture the idea that something turns into nothing, using a single word or striking turn of phrase.
"Evaporate" is the closest I got, but it doesn't go far enough and carries with it a reversibility.
"Pass out of existence" and "turn to nothing" are bland but accurate. "Turn to dust" also leaves a residue, and invokes Tyrion's famous threat.
So, I've run dry.
Paradoxically, there are many great ways of saying that nothing turns into something. Of course there are...
Edit I don't believe the exact sentence will be helpful in this instance, but here's some context to back it up.
The character is talking about how the achievement of his goal will make all the crimes committed in it's service irrelevant. But it's not so much irrelevance, instead the notion that they will never have happened at all.
The sentence: "When we achieve our goal, all this will [insert phrase here].
Another candidate is, "be undone". That's okay, but implies the crimes and their effects being rectified, not simply ceasing to have happened.
Edit 2 A note about the audience: The book is in the action/adventure genre and targeted at adult male readers.
The character is a well-educated male in his thirties, and so is the character bring addressed.
