Merciless

A merciless slaughter was committed in Srebrenica in 1995.

Old age is merciless.

Death is a mysterious, merciless lady.

Be merciless.

Tom is merciless.

He is merciless.

Sami was a brutal merciless killer.

The Vandals were known for their merciless brutality.

I'm merciless.

He's merciless.

The sun is merciless today, so please take care of yourself.
