It is hard, if not impossible, to single out aspects as indicators of any kind behavior as astrology is a holistic process, and thus a whole chart must be taken into account.
For example, a Mars square Chiron could be an indicator for violence, but what if Mars is in Libra (amicable), and the square to Chiron is an "in-element square," as Chiron is in Gemini?
Or, let's say Moon is square Mars, but Mars is in Pisces and Moon is in Sagittarius, and Jupiter (the ruler of both according to tradition) provides a trine to the Moon from an "out-of-sign" aspect in Cancer? Jupiter, moreover, is exalted in Cancer. That softens the "blow" Mars makes to the Moon significantly.
