无情的 用英语怎么说

In English, the word "无情的" is translated to "ruthless." This word comes from the Old English word "ruth," which means "compassion or pity," and the suffix "-less," which means "without."
For example, one might say:
"The ruthless dictator showed no mercy to his enemies." (无情的独裁者对他的敌人毫不留情。)
Another example sentence could be:
"She was known for her ruthless ambition and willingness to do whatever it took to succeed." (她以无情的野心和愿意不择手段取得成功而闻名。)
