You give a hearty laugh at the expense of the foolish rich squirrel, who you've just robbed. Thinking of it as "robbery" kind of makes you feel bad, but rationally you know that this is definitely more of a Robin Hood situation.

Really you're doing him a favor by helping with his hoarding problem. Yeah, this all makes a ton of sense and is completely justified.
