Pions, Why did Kay get everything she wanted after all the evil she has done?

Kay tormented Charity for 5 years until she drove her out of town, and how come she never got punished for this. She froze Charity in a block of ice, tried to send her to hell, spilled fish guts on the poor girl in her prom, impersonated her and slept with her boyfriend, the list goes on. How could someone as evil as Kay get everything she wanted. Evan Ivy, she was probably worse than Kay and she got what she wanted. Gwen gets arrested in the last episode, but she had never been as evil as these two. I thought that Kay should have ended up with Fox because they were one of my favorite new couples and Miguel should have ended up with Charity, and don't even get me started on Luis and Sheridan, because that was the biggest mistack that they didn't end up together, all those years that I waited for them to get together, and not end up together was a slap in the face, and they even had a child together.
