do someone little credit的翻譯問題 - 英檢

眾文TOEFL iBT 托福分類字彙，第7篇，The Third President

第三段最後一句

However, in the trial that followed the suppression of this Burr conspiracy, Jefferson's personal animosity toward Burr and toward Chief Justice John Marshall did him little credit.

書上的翻譯是，"但是，在鎮壓伯爾陰謀叛國行為之後的審判中，傑佛遜個人對伯爾及首席大法官約翰‧馬歇爾的敵意卻為他自己帶來不好的評價"



do him little credit在key sentences的翻譯是，"為他帶來不好的評價"

但是do someone credit的翻譯在
The Free Dictionary是to add positively to the reputation of someone.
Oxford是Make someone worthy of praise or respect

little的翻譯是，一點點、少、稍微、小 這些
不管怎麼說，都是"為他提升一點點的評價"才對

那為什麼書本上卻是翻譯"為他帶來不好的評價"呢？

謝謝各位
