冷血无情用英语怎么说

"Cold-blooded and ruthless" is the phrase used in English to describe someone who is emotionally detached and has no compassion or mercy.
The phrase "cold-blooded" refers to the literal meaning of having cold blood, which is often used to describe animals that are cold-blooded, or those that do not have warm blooded bodies like humans. This phrase is often used to describe people who are unemotional and detached from their actions, as if they have no blood running through their veins.
"Ruthless" means having or showing no pity or compassion for others. Someone who is ruthless is willing to do whatever it takes to achieve their goal, regardless of the harm it may cause to others.
Example:
He is a cold-blooded and ruthless businessman, who will stop at nothing to make a profit.
