The purpose of God's judgments is to get the world's attention. No one knows how to do that like God. This is where the locusts come in, and the rest of the traumas of the book of Revelation. People who now dare God to show Himself will be sorry when He decides to do it. God's ultimate goal, however, is to save the world. In the end, He will do just that. Judgments come for a night, but joy lasts forever.
