Allow us to explain: the person that created this video is not trying to glorify Chris Brown or what he did in any way, in fact the creators were trying to comment on the public's love and appreciation for Chris Brown despite the fact that he beat up Rihanna and continues to show little remorse about it.
From youtube: "Some of the dialogue in this video is taken directly from Chris' twitter post after his Grammy win, as well as the Chris Brown / Rihanna police report".
And in case you forgot exactly what Chris Brown did, this is from the police report regarding Chris Brown attacking Rihanna, reprinted by MTV.com:
"Robyn F. (Rihanna) turned to face Brown and he punched her in the left eye with his right hand. He then drove away in the vehicle and continued to punch her in the face with his right hand while steering the vehicle with his left hand. The assault caused Robyn F.'s mouth to fill with blood and blood to splatter all over her clothing and the interior of the vehicle. Brown looked at Robyn F. and stated, 'I'm going to beat the sh-- out of you when we get home! You wait and see!' "You can read the rest of the police report here.
