Is it right? No. but unfortunitly, thats life.
Human Beings are one of the few animals on the planet that kill eachother out of anger, or for some reason other then for survival. We are capable of horrible things, yet capable of great beauty as well.
there are 6.7 billion people on this planet. We're all not going to be nice people.
And as much as this is disturbing, you go into a larger city, this is common place. I used to live in Winnipeg Manitoba, a city that for several years had the distinction of holding the title of "Murder Capital of North America" because it had the highest murders per captia. And last year, when I was living in Calgary Alberta, a woman pushed a teenager on to the tracks of the C-Tran just as it was coming into the station, killing him instantly. She didn't have a reason why.
We're a terrible species.
