Keep in mind I am Catholic. Catholic teaching on hell is that God sends no one to hell, which is defined as eternal separation from God. People choose a closer existence with God or an existence separate from God.
While it is not formal teaching, some Catholic Saints who had visions of hell noted it was not a place that God built, but rather a place turned over to Satan who made of it a terrible place people of faith dread. Again, not formal Catholic teaching, simply stories told by Catholic Saints who say they were given such visions.
Further, the etymology of "Fear of the Lord" is not synonymous with 'afraid' but more synonymous with 'awe'. It is that awe that draws us to Him. It does not make us afraid of Him.
All this being said, deliberate disobedience is certainly a turning away from and rejecting God. It is choosing separation. If we are not interested in God and His ways in this life, it is doubtful we would be interested in Him and His ways for an eternity. What say you?
