Why Would Somebody Do This?

I know. I get it, there are people who lack any kind of mannerisms, but if anything, this bothers me so greatly. It’s such a vile and disgusting thing to do. Not only because the victim is an elderly, but also because the same person is a WWII veteran.

And it’s not just that. There were also the teens in Oklahoma (I think?) Who killed the Australian man, because “they were bored”
I dont get it. Why is it so hard to keep the young from “the streets?” A simple hobby like yoyoing can do wonders! I thought that even if you were born in a family that was in the wrong, you can be inspired to be the first to succeed. But then again, that’s just my hopes.

Because there will always be evil in the world, unfourtunately.
