Chaney was an idiot
Giving a 5K to Speedy? LOL. The fact that he showed up risking his hard earned money to save Speedy's arse was more than enough but also giving a half of his stash to a guy who would sell his own mother for a few bucks is beyond inane and simply inconceivable.
Speedy only saw a piggy bank in Chaney, not a friend. A guys like him are too self centered and self served to have a friends. And that makes Chaney's gesture even more stupid.
