Do you believe that most people in the world are good people? Does the news just want us to think everyone is a murderer and thief?

You're asking the BIG question. What's the nature of humankind?

Not everyone is as bad as they can be, but no one is as good as they should be. If we're as bad as the news makes it sound, we should be extinct by 3pm next Thursday. But if we're as good as many think we are, we should have eradicated suffering from the planet long before now.

I believe that is somewhat true.

If it bleeds it leads.
Fear is the easiest emotion to 'sell.'

Yes. The news is part of the horror movie genre.

Neither good nor bad. We do what we choose to do. Consider that the news is ratings driven(in order to sell air time), so what we get is rubberneck bullshit-death, dying, destruction, etc. If a Martian landed on this planet, with ONLY the knowledge of the media, he/she/it would expect wall to wall race rioting, with caravans of celebrities being paraded down the streets. We all know that's not true, so don't believe the hype!

No most are arseholes,who will stab you in the back every chance they get
