In one’s life, one has to meet many people. Normally when meeting bad people, one tends to avoid associating with them, unless one shares their liking for doing bad things.
It is considered right to avoid such people, but one should use one’s own conscience, without emoting, to ask oneself why they might be bad, and then try to answer by oneself, the reason why they are. In the process of answering to oneself, this will lead to knowing and understanding who deserves to be called a “Good Person”.
