A mature player will be aware of how certain actions make them look and perform them to suit their purposes regardless of alignment. Now that you know they know what they're doing, it's up to you what to do with that information.

Of course, the idea that they approach the game differently from you is open as well. In that case, you should try finding another way to read them, since your first attempts haven't worked.
