ruthless
pitiless / cruel / relentless / uncompromising
Adjective
This term describes a cold, calculated indifference to the suffering of others. It suggests a psychological state where empathy is entirely absent or intentionally suppressed to remove any emotional barriers to action. While often associated with villainy or tyranny, it can also be used in professional contexts to describe an aggressive, uncompromising drive for success. In a business or competitive setting, the word carries a dual nature. It can be a critique of a person's lack of ethics, but it can also be a grudging acknowledgment of their efficiency and unwavering determination to win at any cost.
