This scripture talks about how God didn't spare the angels that sinned, but he cast them into hell to await judgement. He destroyed the world in Noah's day and also Sodom and Gomorrah because of the sin that was there. In both instances He delivered the godly, those who were living the best they could for Him, but He destroyed the wicked.
I've heard a lot of people say that God would never send them to hell because He is a loving God. They are right. God will never send anyone to hell. Anyone who ends up in hell at the end of life's journey does so because they chose to go there. Why, I'll never understand. God is a loving Father and He gives everyone a free choice. What will your choice be? Heaven with all its splendour or hell with all its torments?
