The ass will carry his load, but not a double load; ride not a free horse to death.
Miguel de CervantesIt is not the responsibility of knights errant to discover whether the afflicted, the enchained and the oppressed whom they encounter on the road are reduced to these circumstances and suffer this distress for their vices, or for their virtues: the knight's sole responsibility is to succour them as people in need, having eyes only for their sufferings, not for their misdeeds.
