Joe really does not deserve all the love and care he gets from those around him. They treat him like a prize (especially Danpei) but he creates and/or worsens his situations needlessly.
It is admirable, and perhaps something noble, when someone continues rising again and again from hardship (in life or in a boxing ring), but not when that person is the one putting himself in those situations needlessly and often at the expense of those around him.
