If someone's spouse and kids don't believe there is no point to it because it's not eternal. For a man marrying an unbelieving woman, she is more likely to kill your kid with abortion or raise your children trans or with guilt for race or other categories. Then the children are raised evil. 

If a woman marries a man who doesn't believe, then he is the leader of the family and the children become unbelievers. She is then forced to abide by ungodliness and submits to evil. It is better for someone to have no children at all or no spouse at all than a child or spouse in hell. We are living for the kingdom of heaven.

I do think that a great mind with well constructed morals is not necessarily a catholic one. You will have pedos, sluts, drug users, etc. inside and outside the church, being catholic is not a guarantee that your couple is going to be a good one.

I think that you are being a bit too tight with your thoughts OP. For me, a gurl that barely or doesn't go to the church BUT helps in an asylum, tries to help the poor (giving money is not everything and usually corrupts some) or some shit is more 'valuable' than a zealous girl.
