If you are doing the killing then there is a need or desire to kill off, to put an end to something in your life such as a relationship, a behavior, a situation, etc.

If someone is trying to kill you, then ask yourself if you are feeling pressure to make some changes in your life to put an end to something.

If someone you know is being killed, ask yourself what sort of change they may be going through right now, OR perhaps your relationship with them is changing or is endangered.
