Not only isn't he sure that he will be able to gain karma if he lets someone else do the giving in his stead, he also isn't sure that these people will actually give people the loaves of bread. So he rejected their goodwill.

He watched them leave with regret. "It seems they are smarter than they look."

He had enough experience to identify them as bullies. What he had said about his charity interfering with their charity was a joke. He expects them to be thugs who take advantage of others.
