Spoiling a child, especially after their become adults and do wrong things is failing your child and the world and if they go wrong at least give a step back and let them learn the meaning of consequences.
Is to send to the world someone that will be a good add to this world in their own way, even if just a little or even if their choose a wrong path you can say that you really tried your best.
Raising a child well is not coddling to their every mistake and sin, covering up their crimes or favoring them over your other children, is to educate them to be a good human, to have responsibility, compassion, dreams, etc.
