It's not a question of 'deserve'. He put himself in a ridiculously dangerous situation and he got killed.
I don't understand the anger at Stallworth. He wasn't particularly hammered, and by all accounts, he was devastated at having killed someone. This could have happened to any one of us who was changing a radio station or looking at a cell phone at the wrong time. It's not even clear alcohol had anything to do with it.
I know I've personally been behind the wheel after a couple of drinks many times. Had someone jumped a fence and jaywalked the freeway in front of me any of those times, I'd be in the same boat Donte's in, whether or not my driving had actually been compromised at all.
