10. Shooting Pam To Stop Her Blabbing
Apart from crocodiles, alligators, and brain aneurysms, one thing that does scare Sterling Archer is people finding out things he'd rather keep quiet. Over the years, this desire has seen Archer do some pretty terrible things. The worst of which has to be shooting his friends to stop them blabbing.
Admittedly, it can be argued that getting shot is just an occupational hazard of working at ISIS, especially if your name is Brett. However, getting shot for nearly spilling a secret seems a little excessive.
While Archer has done this on a number of occasions, the worst has to be when he shoots Pam in the chest with a M41Plasma Pulse Rifle while onboard the Intrepid space-shuttle. The only reason he does this is because Pam was about to tell everyone Archer snuck her on the ship "on the off chance he wanted to bang".
It should be made clear though, that Archer shoots her with the rifle’s 'stun' setting. But this actually makes it even worse, as only moments before, Archer shot Cyril on the same setting. This caused Cyril's heart to stop, effectively killing him until he was revived after being zapped by a defibrillator.
Therefore, Archer is well aware that there is a relatively high chance she could die when he shoots her, which, like Cyril, she does for a few minutes before being brought back. So essentially Archer was willing kill Pam one just so the gang wouldn't know he was sleeping with her.
