请分析一下这句话中would have done 的意思：We would if we were taught to

给你看原文和别人的翻译,参考下：
We would if we were taught to put the fish back when we were young.For we would have learned the truth.The decision to do right lives fresh and fragrant in our memory.It is a story we will proudly tell our friends and grandchildren.Not about how we had a chance to beat the system and took it,but about how we did the right thing and were forever strengthened.
在我们还小的时候,如果有人要我们把鱼放回去,我们会这样做,因为我们还在学习真理.正确的决定在我们的记忆里变得深刻而清晰.这个故事我们可以骄傲地讲给朋友和子孙们听,不是关于如何攻击和战胜某种体制,而是如何做正确的决定,从而变得无比坚强.
