A snake does not become less dangerous because you understand why it bites.

Understanding why someone does harm can be genuinely valuable and it changes nothing about what they will do next. Explanation frequently gets mistaken for a kind of safety, as though comprehension were protection, and people stay close to something harmful because they have made sense of it.

Hold the understanding and adjust your distance anyway. Ask what the person has actually done repeatedly, not what caused it. Compassion and caution can both be true, and one does not cancel the other.
