I think that you are to pessimistic person and believe media to much.
World is not ideal, perfect place to live, it's true but also is not hell or dark place for living.
World is more like gray place, with god and bad things mixed.
You have many world organizations and politicians which helping people, as much as they can (for example Merkel in Germany accepted a million refuges from Middle East) but, of course, you have people as Assad, president of Syria, who attacking his own people in Syria and don't want to give them peace and freedom.
Terrorists are usually independent and have their own agenda, like ISIS.
In fact, all the world united against ISIS now.
