It's complicated. Spinel was subjected to solitary confinement (which makes you do crazy things) for 6,000 years. To say that had a detrimental effect on her sanity would be an understatement, and she likely lost her sense of morality in the process. She also admitted herself that what happened to her doesn't excuse what she did and was remorseful over her actions. As for Pink, the Diamonds made Spinel for her. She likely wouldn't have gotten in trouble if she brought Spinel with her, and it's made clear that Pink abandoned Spinel because she saw her as nothing more than a toy she got tired of and thus she left Spinel behind, even going as far as to use a trick to get Spinel to stay in the garden.

And for your "theory"... it makes absolutely no sense. If Earth had been destroyed, Steven would've been dead and he wouldn't have gotten to live on Homeworld with them. Also, if the Diamonds wanted Earth to be destroyed, why did they come to Earth to live with Steven near the end of the movie and asked Spinel to live with them on Homeworld?
