What is wrong with the world?

Today, 26 people died in two shootings. One in Alabama, one in Germany. I haven't read the details of the shootings really, except for the fact that there was no reason for them (is there ever a reason to kill innocent people). If the shooting had just been in the US or just been in Germany or centralized to somewhere not here, then I would think that there had to be something wrong with that particular place, but this is on opposite sides of the ocean. There are pictures of people sobbing, a story of a deputy who's wife and daughter were killed in the Alabama shooting who was saying "it was supposed to be me." It's all a tragedy. I'm not a peace love, and happiness kind of person, but I do believe in peace, love and happiness. And having respect for the human life. It's mind boggling that there are people who can just open fire and not care who goes down, especially not themselves, since often after causing their destruction, they kill themselves, which is the case in at least one of today's shootings. It's such a tragedy that there is no value to the human life anymore.
