As with fighting, struggles can mean conflict with others or perhaps your inner self. Killing can represent a stronger emotion and that you want to bring this conflict to an end.
Are you working on a project that you just want to be done? Is someone in your life causing a lot of commotion or unhappiness?
Think about close friends or relatives - would you like someone to just go away and leave you alone? As with a fight dream, you may feel threatened and you want to end the situation.
