I went to college for journalism and in one of my classes we were taught about "mean world syndrome". Basically it means that in order to get views, news teams pick the most horrendous things to report on.
For example which newspaper are you more likely to look at, one that says "EBOLA TO WIPE OUT HUMAN RACE?" or "EBOLA KILLS ONE PERSON, 99% OF PEOPLE UNAFFECTED"
Because of the media doing this people fall victim to mean world syndrome which leads them to believe the world is actually a much meaner and unsafe place than it actually is.
In reality the human race is both good and bad but we are lightyears ahead of where we once were in terms of ethics.
I hope this makes you feel better. There is so much good in the world, but it goes unnoticed because our brains are hardwired to focus on the bad.
Hope you feel better
