Kill Bill Why was Bud such as loser?

Mostly speculation; but any thoughts why Bud winded up as a bouncer in a titty bar with a shtty trailer and no money? He was part of the viper assassination squad so obviously had some talent before.
was he also trying to run away from his old life or just had some depression/guilt issues?
And yet, he was the closest in killing Beatrix, right?
