The consequences of keeping a bag full of money found can be quite severe. Legally, in most places, it is illegal to keep someone else's property without attempting to return it. If the owner reports the loss and there is evidence that you had the bag, you could be facing criminal charges. This could result in fines or even imprisonment depending on the value of the money. Morally, it goes against basic principles of honesty and integrity. You would likely carry a sense of guilt with you. Moreover, it could also have social consequences. Your friends and family, if they find out, might view you differently. They could lose respect for you, and it could strain relationships. In a community, your reputation could be severely damaged, which might affect your future interactions and opportunities.
