A: I've tried to be kind to him against my better judgment.
B: What do you mean by that? Didn't you know he was not reliable?
A: Yes, I did. But I wanted to give him another chance.
B: Now you know he won't change.

A: 我一直尽心善待他，虽然明知不智。
B: 这是什么意思？难道你不知道他并不可靠吗？
A: 我知道。可是我想再给他一个机会。
B: 现在你知道他本性难移了吧。

 

重点解说：

★ against my better judgment「虽然明知不智」此语表示虽然明知做某事是不智的或不可取的，自己仍然没头没脑的做了。类似用法如:He is a man of good [poor] judgment.「他的判断力很好/很差。」"Don't be judgmental."一语也很常用，意思是「不要主观的下判断。」

★ reliable「可靠的，值得信赖的(=dependable, trustworthy)」
