Tristitia - one of the deadly sins.
Why is despondency considered a sin?
According to the holy fathers and theologians, a certain type of people who are "sick" with yet another sin - pride - are subject to this condition. In a state of pride, a person believes that other people and circumstances are to blame for his problems and sorrows. It begins to seem to him that everything is going awry, and there is no way out of such situations. At the same time, he does not try to find the cause of failures in himself, his behavior. The danger, according to the priests, lies in the fact that a person does not want to accept God's will for what is happening and gradually turns away from him, becoming more and more mired in pride. In the end, a person driven to despair by his own bleak thoughts can commit another grave sin - suicide, which will forever close the path to Paradise for the sinner.
