Well, no more for past atrocities than for this atrocity should we make piety responsible. At most we may blame piety for not availing to check our natural passions, and sometimes for supplying them with hypocritical pretexts. But hypocrisy also imposes obligations, and with the pretext usually couples some restriction; and when the passion gust is over, the piety may bring a reaction of repentance which the irreligious natural man would not have shown.
