At the end she did her best for her followers and friends, but her mistakes were too large to ignore. That misstep led to Earth’s Corruption, and the thousands of years of suffering and bestial madness that followed for almost every Gem left on Earth.

The toll on prehistoric human life must have been similarly terrifying, as godlike superbeings battled not just on the planet’s surface but deep within it. The psychological damage inflicted on the Crystal Gems and Homeworld Gems alike is horrific. We see the fallout from the Gem War everywhere in Steven's universe, from the Corrupted Gems to Lapis’ mirror. If Pink had learned to talk to the other Diamonds she could have saved billions of lives. Instead of speaking out against the injustice she saw she faked her death and provoked an interstellar war.
