~Executioner: Could be a system member who tends to be a bit aggressive or off-putting to others who feels the need to interject themselves into arguments outside of the headspace.

Their goal is not to protect themselves or anyone else in the system, but to try to have their feelings and opinions on the matter heard. This can but doesn't have to include system members who may sometimes purposely and personally mess up relationships outside of headspace that they deem "not important", "not worth while", or they believe is somehow harmful to them and maybe even the whole system, even if other system members don't agree that this is the case.
