The aspect of not being sure if things are bad or good is what keep spoiling things and making them worst. Noting or identifying what is good from what that is not good is very very important. There are things we do or practice, does it cause more harm than good to us, but because of one thing or the other we tend not to stop this behavior or attitude. Some persons it could be what they eat, what they drink, the behavior of life, or attitude.
Noting what is bad, is not majorly just for l, what we eat or what goes into the mouth. In many cases our behaviors may be dangerous, and can cause more harm. Somehow we tend to continue practicing this behavior, an approach it like it is normal, going fully well that there are consequences attached to all the behavior of ours.
In Our society today, young youth are addicted to alcohol and drugs. Is it children of 17 years doing many drugs, many are involving smoking and all sort of bad behaviors.
When you tend to advise them, you become the bad person. So you don't know what to do, either to advise them, or to allow them face the consequences the caused by themselves. In many cases I will prefer to say, do your part and for your conscience. Whenever your conscience is not judging you over something that means you are on a safer side. Then, back to the prompt.
Knowing fully well that smoking, doing drugs, and becoming drug addicted have consequences, it is just a pleasure of a moment with the consequences of lifetime. But some youth prefer to face long-term consequences, than to prevent it. Which ideally, it is causing more harm, than the pleasure it comes with.
