About violence.

Therefore, there are five different traits,
that are dangerous in general.
Those who are ready to die
can be killed;
those who are intent to living
can be captured;
those who are quick to anger
can be shamed;
those who are puritanical
can be disgraced;
those who love people
can be troubled.

-Sun Tzu, The Art of War (quoted from an email I got from Sanna today)
