Judging a book by its cover

Society plays an important role on how an individual turn out to be.
Society in this case can include - Friends, family and strangers.
Technically, when someone is involved in a negative action, we automatically reply to the action with a negative reaction. We don't question them on why did they involve themselves in the negative action in the first place. We just jump into conclusion that they are bad people. On top of that, we ask others to stay away from them. Indirectly banishing and isolating them from everybody that could have helped them to get out of their misery.
Why judge a person when you don't know their story?
Why don't we question the possibilities?
Why?
An innocent girl could be putting herself in the market tonight, risking her reputation and neglecting her value  for the sake of earning some money for food. Society, would not question on why is she doing so. Instead, they just label her as a whore. A cheap slut. Nobody questions her story and reason of why she is doing so. Men, on the other other hand, support the act by buying her for a night of erotic pleasure. Why can't they stop her? Why didn't they help her? Human trafficking is bad, we all know that. However, those whom support the continuation of it is worse than an animal! Think about it. Why is it that human trafficking a never ending battle? Because, no matter what money still comes in for the those whom supply. Profit is still there. Why? Because, people have been supporting it. It doesn't have to be you or me but, someone out there is still doing it. Why didn't we question of why it did not stop? Most campaigns have their efforts but, they are still hypocritical. Nothing stopped. Why waste money and time on it? Supporting a campaign to stop human trafficking is not enough to stop it. Yes, we have saved many lives but, why hasn't it stopped? Why? Ask yourselves. Why?
When we see a  girl selling herself on the street and we never stopped to ask her what her name is? Why is she doing it? Who made her do it? How to save her? We just walk pass her, labeling her with all kinds of name. When we do save those people, we still exploit them for a good story to be published in a newspaper or even a book. We support the campaigns to stop human trafficking but never once act to stop human trafficking.
Well, leave that a side for a moment and lets investigate on the most common and simplest issue; 'Smoking'. We all know that smoking is bad. However, we can still find products of tobacco being sold almost everywhere. We hypocritically support the non-smoking campaign but, nothing good has ever come out of it.  There are still people out there with a cigarette lit in between their fingers never bothered of what ever kind of campaign is out there to stop people from smoking. For some reason, I prefer smokers than those whom support human trafficking either directly or indirectly. Smokers kill themselves slowly, while those whom support human trafficking take away others' life by owning them for their own pleasure; technically man slaughter. Like it or not, that is the term best fit for them I'd say.
I do not blame everyone. I just want people to stop for a minute and think about it. Why does society constantly judge a book by its cover and hypocritically support campaigns that are merely for the use of publicity?
