You damn people whose wills are so weak that they cannot avoid sin!

The Catholic Answers

None but deliberately willed and unrepented mortal sin meets with eternal punishment. If inherent weakness is so great as to destroy real responsibility, God would not accuse the man of mortal sin. But such is not the case with the normal man. The normal man is able to refuse consent of the will to evil inclinations and suggestions. Some people are only too ready to call their own cowardice inherent weakness. They could have refused to sin, but chose to sin, and afterwards fell back on the lame excuse of “weak moments.”
