I don't know....what's the point of posting this? One 27 year old guy is obviously insane did a terrible thing. So is this to then prompt a discussion about how horrible the human species is? I just don't want to play that game, no thanks.
As the article noted, many people got involved and tried their best to stop the man to no avail. They didn't cheer him on in demonic pleasure, or pull up lawn chairs and watch the murder while eating popcorn.
No, other people tried to stop him, and police arrived and had to kill him. But it was too late to save the child.
Some people are not mature enough to be parents, if that is the case here. Taking care of a small child is hard work, as I am sure many people here know from personal experience. A child is totally self-focused, cannot empathize with your needs or pains, so a mature adult has to set their own needs and pains on the "back burner" in order to tend to the child's need. I understand a child cannot even begin to empathize with others as separate beings until around 7. So a child just being a child, with the times of non-stop crying and whining and neediness, can just be too much for a person who is very wrapped up in their own needs. Who knows what rage was projected out from years of pent up anger against that poor child.
But is humanity just no damn good because of this? No. I'd say the statistic is about 20% "bad" (anti-social, self-centered, destructive, hostile) versus 80% who just want to earn a living, take loving care of their families, and get along with others.
We each have the potential to be demons or angels. It is a moment by moment decision. If you want to see all of humanity as scum, then that reflects that you secretly also see yourself that way. I don't identify with that 27 year old man, although I can understand how someone could "snap" and do such a horrible thing.
