Yea. I'm not trying to say that what they did wasn't wrong, just that it's not completely unheard of. You've never heard of people being beat to death on the news? I know it may sound kind of weird, but I do see it every now and again.
Edit: Also, hopefully the curiosity of people won't get the better of them. Personally I haven't watched these video's, but I know what they are like. In all seriousness I would suggest to not watch them.
