Pessimism

"a tendency to see the worst aspect of things or believe that the worst will happen; a lack of hope or confidence in the future."

"Philosophical pessimism is not a state of mind or a psychological disposition, but rather it is a worldview or ethic that seeks to face up to the distasteful realities of the world and eliminate irrational hopes and expectations (such as the Idea of Progress and religious faith) which may lead to undesirable outcomes"
