We have begun the wonderful discipline called 'timeout'in our home with our toddler. Certainly, you recognize some variant of timeout from your growing up. I certainly do. Mine (and my daughter's) took place in the corner. It is discipline which makes you stop for a second, step away from that poor choice, and 'think about what you have done'.
I do not want to see my girls keep getting hurt by their bad choices. So I discipline them for the bad choices in HOPES they will not continue to be harmed by them.
"For those whom the Lord loves He disciplines...but if you are without discipline, then you are illegitimate children and not sons/daughters...For we are disciplined for a short time as is best for us and our good. All discipline for the moment seems not to be joyful; but sorrowful; yet to THOSE WHO HAVE BEEN TRAINED BY IT afterwards it yields the peaceful fruit of righteousness." (Heb. 12.6, 8, 10-11)
God will let others fall under the weight of their sin, but not his children. Children without a Father are illegitimate. Children without a Heavenly Father are eternally illegitimate.
But to those who belong to God will be disciplined for our poor choices in HOPES we will not continue to be harmed by them. We are disciplined in hopes we will learn from those things which keep harming us.
