It's all about the spine guys. Break the spine and you kill the shifter. In Chapter 79 if Mikasa had cleaved Bertolt in half through his spine, then the vital essence would have poured out and Bertolt would be dead.

" Eren is fearing for his life when a gun is pointed at him"

Eren is still thinking like a non-shifter human, a gun pointed at his head is still bad news. Maybe Eren would lose some memories because he doesn't have a titan brain to backup his memories to but as long as his spine wasn't compromised, he'd reform.
