Abaddon is practically unkillable. I'm quite certain he could tear Stern to shreds. She has what, a decade of combat experience? I believe the only ones able to kill Abaddon would be the Emperor or Magnus the Red as they are the two most powerful psykers in the galaxy. When the Emperor killed Horus, he actually annihilated his soul, so the chaos gods couldn't resurrect Horus because there was nothing left to resurrect. The same would have to be done to Abaddon so he doesn't come back. Magnus is probably the only psyker powerful enough to do that, and he knows a lot about chaos and the warp and such.

As for any inquisitors, Abaddon would slaughter them like children. No human psyker could ever overcome the sheer number and power of the number of daemonic pacts Abaddon has protecting him.
