ruthlessness

This term describes a cold, calculated lack of empathy, often associated with a drive for power or efficiency. It carries a strong negative connotation of cruelty, though in specific professional or political contexts, it is sometimes framed as a necessary trait for survival or dominance.

As an abstract quality, this noun is uncountable. It cannot be pluralized or counted as individual units; instead, it is measured in degrees of intensity or described using partitive constructions if referring to specific instances of the behavior.
