House of God - Zmola

Is there any way to not kill Zmola?

I’ve done the quest up to the point where I’ve let Leshek go (found him in the Mill) and now all I have to do is confront Zmola.

The options I get though are Kill Him, Ask Him To Explain and Take Him To The Overseer. Both of the last two options ends with him fighting you, so I knock him out, then he gets up and just starts running.

bring Leshek to the overseer as a witness. Guards will then be sent to arrest him. I believe they will end up killing him.
