Sister Wives star Robyn Brown may be one of the most-hated women on TV, in large part because of what she's done to Kody Brown's life. While her patriarch hubby's no angel (he recently compared himself to Satan), Robyn's more than a little devious. Since she doesn't shoot from the hip, preferring passive-aggressive tactics, she may be the real reason why three wives ran for the hills. Onscreen, in season 18, Janelle and Meri Brown are still trying to make things work with Kody, but they're getting nowhere. Offscreen, IRL, they both bailed out, just like Christine Brown, who led the exodus.
