ruthless
Showing no mercy
Ruthless describes someone who pursues goals without mercy or compassion, willing to harm others or ignore their suffering to get what they want.
A ruthless dictator crushes opposition.
A ruthless negotiator exploits every weakness.
The word implies cold calculation—not hot-blooded cruelty, but deliberate disregard for others when they stand in the way.
