12 Most Shocking Betrayals In TV History

10. Stahl Kills Her Girlfriend - Sons Of Anarchy

Sons Of Anarchy has some seriously explosive moments and Gemma's murder of Tara could have qualified here if it wasn't for the fact that it was actually in response to a wrongly assumed act of betrayal in the first place. So Gemma is off the hook, just about, even though she was a despicable monster all the same.

No, the real worst betrayal in Sons Of Anarchy comes in the third season when Agent Stahl proved just how far she'd be willing to go to climb the ladder at the ATF. Having been demoted and removed from the IRA case in the wake of her murder of Edmond Hayes - and framing of Gemma - she needed a scapegoat for Hayes' murder and settled on her own girlfriend, Agent Amy Tyler.

The pair were lovers, they lived together and Stahl turned all of that on its head for the sake of protecting herself and her career. And have no doubt that she genuinely loved Tyler - her love simply wasn't as strong as her evil.
