I do feel like people are being quite rude and judgements, of him, but stealing art IS wrong. There are people who have slaved away, working hard and spending hours of the day working on the piece. Day after day, they come back and continuously pour their soul into their artwork, and this person is just taking all of that and stealing it away. It is, if not anything else, rude, and showing a complete disregard for other people's hard work.
