A Catholic should pray unceasingly for the good of their soul and the souls of others.
However, when we start saying that others are destined for Hell, we are putting ourselves in the place reserved for Our Lord. It's not our call to make. In fact, by making this call we are being presumptuous and uncharitable.
Having said that, the actions of many in the secular world are annoying, bewildering and discouraging.
--- Pray for the souls of others.
