You give rise to a lot of thoughts lurking in the back of peoples minds Im thinking. Most of us though have a moral code and would not consider doing these types of things. However this is how people get scammed because by default we absolutely believe the rest of the world thinks with a moral code attached to actions.
In many cases they do not think like us!
Think of what has been done to people in the name of Religion/protection of sovereign interests/oil/gold and just plain insanity etc.
Genocide WPM/Nuclear Torture Bombing of civilian cities School massacres Ethnic cleansing etc etc
Let all of these events that have happened temper our trust of these events and understand that most of us don't expect these events to happen to us until after it has happened.
