How could anyone ever try and ruin someone for doing the RIGHT thing?

Peyton/Mrs. Mott knew that her husband had sexually assaulted other women and cheated on her during the time she was pregnant, and she decides to ruin the woman who took a stand for this and help other women? Her husband was a scumbag, and she had to have known it at least after the cases were made public.
It's sad that some people sympathize with her, even though her loss was tragic, she could have released she was as much as a victim as these other women when he killed himself.
