One day, the destroyers of the earth (unrepentant sinners) will themselves be destroyed, and God's people will inherit a new Heaven and a new Earth, without sin! So the Good News is truly good news to some, and bad news to others. In this way, the true Gospel is hardly inoffensive; it is an outright offense to the unregenerate, as it must be. A gospel that doesn't require the shed blood of Jesus to pay for our sin is a false gospel.
