If there would be no thieves or crimes ,no need of any police ,lawyers or judges.Without bad people,nobody can differentiate between bad and good persons.So in every societies we we are bound to adjust and live between these two elements GOOD and BAD.May it be Junk foods,persons or anything else.It is up to you to decide, whom to follow !Good people or bad people, Junk foods or home cooked foods.I would definitely go in favor of home cooked foods and good people.
