If a family is unable to take care of their kids, should they continue to have kids?

[EasterJoy]

Let’s go back to the analogy of drinking. You as a bystander don’t have the right to determine whether a person is going to get drunk. It is up to the conscience of the person actually imbibing alcohol. Nevertheless, self control is obligatory on people drinking and depending on the situation, they may be sinning or being virtuous. (Jesus drank moderately- virtuous. Noah got drunk accidentally- virtuous. Someone purposely gets drunk even though they know it is a mortal sin- sinful. To eat, drink,
have sex within proper boundaries and with right intentions is virtuous. To do so out of boundaries is vicious. As I have said before, I am only addressing the larger question of whether a couple who can’t raise kids should have more, and once more I would have to answer that it would be sinful to try to procreate when there is no reasonable expectation of being able to provide for the basic needs of the child.

It would at least be more giving to abstain than not to, when such a situation is recognized by the parents. As your example of Noah indicates, you realize that a couple might choose the wrong course not out of selfish intent, but out of misplaced selflessness. If they discern in good faith, it is no sin if their discernment is incorrect in an objective sense. This would be true whether they judge for or against avoiding pregnancy. Provided they use due diligence to inform themselves and to judge rightly, they can still make mistakes but the mistakes aren’t sinful. These are often not discernments where the couple can always see a bright line between the Right Decision and the others, and that is before the lack of self-knowledge typical this side of sainthood is taken into account.
