Three wise monkeys who teach to 'speak no evil, hear no evil, see no evil' signify refraining totally from evil, yet they also represent 'good people' who do nothing about evil, feign ignorance, and turn a blind eye to misappropriate behaviors. It's possible that evil won't prevail in the society, if good people stop to stand by, and take positive steps to stand up and be counted.
