What does ruthlessness mean?
Ruthlessness is the quality of showing no pity, mercy, or concern for the feelings or welfare of others. In its dominant sense, it describes deliberate cruelty, harsh treatment, or a willingness to cause suffering in order to achieve a result. The word often suggests moral callousness, but it can also characterize uncompromising behavior in business, politics, or sport, especially when competitors are said to pursue advantage without regard for fairness. Even in these more neutral-sounding contexts, “ruthlessness” usually implies that an extreme standard has been accepted and that human considerations may have been disregarded. Derived from “ruthless,” meaning without pity, the word is especially useful for naming both the method and the ethical cost of treating other people as expendable. It can therefore describe a practical, unsentimental approach, but it usually makes the audience judge that approach rather than simply admire it.

Where does ruthlessness come from?
Ruthlessness was formed in English from ruthless and the noun-forming suffix -ness. Ruthless combines ruth, an Old English word for pity or sorrow, with -less, literally giving “without pity”; ruthlessness consequently names the quality of being pitiless. Ruth is related to German Reue and Dutch rouw, both denoting sorrow or regret. Related English forms include the archaic words ruthsome and ruthly.
