If true I wouldn't consider Ray to have been acting on behalf of a conspiracy (even if the bounty itself was a conspiracy), but it's not quite acting alone, either.

They may have already been primed to do something horrendous, but there's an element of but-for causation regarding the particulars and follow-through.
