17. June Kills Her Partner
Season 3, Episode 12: "June Wedding"
One of the show's early villians, June Stahl was an ATF agent who vacillated between tearing SAMCRO apart and working with Jax to cover her own ass. Agent Stahl's indifference to any moral code, however, reached its peak when she murdered her own partner Amy Tyler — who also happened to be her lover — in order to set up the Sons to go to prison. Stahl gets killed herself one episode later, as part of what turns out to have been a nifty long con executed by Jax and Clay. But the show had already sent a clear message: There are no real heroes in Charming, only different shades of ornery.
