remorseless
Showing no regret
Remorseless means without remorse—showing no guilt, regret, or pity.
A remorseless killer feels nothing for victims.
The word also describes things that continue without letting up: the remorseless advance of the disease, remorseless pressure to perform.
Both senses share an idea of something that won't soften or relent.
