The way it’s currently set up is geared towards the murder hobo.
Any DM worth her salt would hate playing with a murder hobo. My younger brother would kill off a murder hobo (if he didn’t refocus) because he said it was no longer fun for the DM and possibly the other players. As a DM he wanted a story to unfold not a hack and slash. He would always reward xp when a player came up with witty, outrageous and/or brilliant ways to advance the story narrative. He could write a book with some of the stories he has.
Are there any XP given at the ruined temple if you talk the group away? I don’t think so, but if you fight them, then yes.
