You can <i>easily</i> separate the concepts via the initiation of force.<p>The murderer is the initiator. ISIS is the initiator.<p>Example: &quot;The US should murder the Japanese people and nuke all of their cities immediately.&quot; Japan isn&#x27;t an aggressor, hasn&#x27;t invaded anyone, isn&#x27;t slaughtering the people of some country they&#x27;re trying to annex (ISIS). Calling for a response to to the initiation of violence, is not the same as calling for the initiation of violence. If you remove these blatant lines, you can never differentiate on a legal basis who is the victim and who is the perpetrator in acts of eg crime.
