unthinking
Done without consideration
Unthinking describes action or behavior done without thought or consideration.
An unthinking remark slips out carelessly; an unthinking habit operates automatically.
The word often carries criticism—suggesting someone should have thought before acting: His unthinking cruelty hurt everyone around him.
Less commonly, it describes someone incapable of thought or reflection.
