Well, I imagine 99.9% of those that drink and drive aren't professional footballers with the responsibilities that come with that. And your sentence does not vindicate him.
The guy's a failure whether or not he's the only "bad egg". He let his irresponsible attitude fail his rational judgement which was induced by alcohol.
He's no good for the club or the team.
Everyone makes mistakes but my feeling is, Hamza was arrogant, drunk and took a chance without thought for the potential consequences.
You seem to want to absolve him in some way, yet you say in the last sentence that you "despise it when people make that choice".
By that statement you condemn Hamza having earlier tried to defend him.
