"When a Benefit is wrongly conferred, the author of the Benefit may often be said to injure"

This quote by Plato suggests that when someone does something good for another person, but it is not should have or appropriate, it can be viewed as an act of damage. To put it simply, when someone does something for somebody else that is not helpful, it can be seen as an unfavorable act. This could be interpreted as a warning against doing favors for people who do not deserve them, as it could be seen as an act of harm. It might also be analyzed as a reminder to believe thoroughly prior to doing something for somebody else, as it might be viewed as an act of damage if it is not helpful. Eventually, this quote by Plato works as a tip to think carefully before doing something for another person, as it might be seen as an act of damage if it is not advantageous.
