谁知道这句话怎么说?

Forgive him for his regret,since nobody makes no mistakes.
之所以这样翻译是因为我觉得句子强调的是原谅他！而原因是他悔过了，为了简洁，就用了一个for句型。
最后又个宏观的原因---没有人不犯错。

呵呵我觉得翻得挺好，

nobody can do everything right,if he repent it,forgive him.

Everyone makes mistakes.Now that he is regret,forgive him.
最简单明了的翻译。

Incapable error of nobody forgives him since he knows having been repentant

There is nobody making no mistake. As he regrets on his doings, let us forgive me.

nobody can do everything right,if he repent it,forgive him.
