How is allowing this person to have no repercussions from this Christian?
They destroyed property, what will they learn from this by not facing consequences?
Will they be more likely to do it again?
What path will avoiding consequences set them on?
We discipline our children out of love for them. Is that un-Christian? The bible speaks often on God disciplining His children to instruct them in His ways, to understand that they’ve done wrong.
Sometimes when we tolerate evil as opposed to facing it, the evil increases.
This person made choices, there are consequences to one’s choices. Certainly, forgive them, bear no ill will towards them, but they certainly need to understand that actions have consequences. Better to come to grips with that over a small matter vice a much greater one.
