I get the message, but I don't think this video did a good job portraying it at all. Let's be honest. That little defenseless kid is still dead, and no matter how shitty the older boy or his dad's life is, it's no excuse for what either of them did. I understand how this works, but I feel like this video tries to rationalize the characters actions with the excuse "violence is a vicious cycle". It was well shot video, with a good message. But I think the execution was poor.
the common phrase "violence is a vicious cycle" has never been used as an excuse. It's pointing out that the effects of violence are even more damaging then what is immediately apparent.
