It is not contributing or being in any harm, after all it is in off-topic. Which again is just having discussions of sort, I don't think much problem with this. I know we have all those other things, but making such discussions here does increase the forum activity perhaps?
I dunno, it's off-topic!
I suppose an - you could call it - attempted murder or torture is not ethical, thus not proper either for a civilized group of people in a community about gaming, plus, most people here might not wanna see something like this, at least when you guys make a topic like this explain what it is about. I don't mind the video, I watched it like 5 times on the news, however some people don't like watching such.
