借刀殺人-------請簡單翻譯成英文

1)to kill somebody by another's hand;

2)to make use of another person to get rid of an adversary

Someone killed by a borrowed knife.

Murdering with a borrowed knife

相信你不是想要這些傳統翻譯。

我會簡譯：
Kill by Hired Hand - 真的犯罪
Annihilate by Weapons on Loan - 戰略

to make use of another person/indirect means to get rid of a rival.

英文翻譯

借刀殺人: to borrow a knife to kill somebody
