Why did the man need to accuse them before they distanced themselves from the city?
Hadar Zekenim: Near the city, the fear of the city is on them. Far from it, no one can confront the Shevatim, who are like Chayos - e.g. "Gur Aryeh," "Nachash," "Ayalah Sheluchah" (Bereishis 49) (Da'as Zekenim).
Why did he need to say, "Why did you repay bad in return for good"? In any case, theft is despicable!
Malbim: There are three reasons why people steal (and none apply here)! (a) It is revenge for mistreatment. My master did good to you! (b) The owner made it Hefker, 1 and it is not important to him. "My master drinks from this!"
