Maybe the gems were going to destroy/take over the earth and the Crystal Gems were sent as scouts but began to like earth life (specifically Rose who fell in love) and couldn't go through with it. So this led to a fight between the Crystal Gems and the home gems (as depicted in the mural of Rose fighting that other gem in Serious Steven) and they had to run away to earth and destroy the warps. Maybe corrupted gem beast are gems who rebelled with Rose (consider they were figures behind her in the mural and look like more than just Garnet, Pearl, and Amethyst) and they became corrput because of damage from the fight/war that occured. Maybe Peridot came to scout and repair the warps so the home gems can finish what they started. Maybe thats why Amethyst was so scared and the Gems were so worried because they are traumatized by the events and to relive them or worse; end up dead or corrput. This is elaborate but it would make sense.
