inhuman

If someone behaves in a way that shows no compassion, you could describe that person and his or her actions as inhuman. A teacher who assigns six hours of homework every night might be seen as inhuman.

When people talk about inhuman things, they're usually not talking about dogs or Martians — beings that are literally not human. Rather, this word involves humans who show no regard for their fellow humans. Murdering another person is an inhuman act; slavery is an inhuman institution. Inhuman acts can also be described as inhumane, meaning “heartless and cruel.”
