People like this are simply proof that the world has far too many goddamned people, who do nothing but take and consume and abuse and cause harm. They add no value to the world, they just take up space and oxygen and precious water. It might be something if once in a while, one of these useless humps sees themselves in a mirror and asks themselves why they bother, why they persist, why instead of seeking to quell their inner demons, they are content to inflict them on everyone around them.
Prince Shembo probably doesn't realize it or believe it, but his NFL career is over. The league has had enough bad press and stupid moves over the last year, and it doesn't need another shithead animal abuser hurting the brand. No team will touch this asshole, he's toxic. Ordinarily that might be enough punishment, but he's also got the blood of a nice girl on his hands, and gives far less than a fuck about her.
This is another one of those infinite cases where you wish Nature, in all her supposed wisdom, could maybe be a bit more selective about culling the fucktards from the herd.
