Is it okay to steal from landlords?

Today's NYT has an article about landlord-tenant law in NYC: Illegal Sublets Put Private Eyes on the Case. Here is a key quote:

“Everybody thinks landlords are bad and we can steal from them,” said Mr. Frankel, a helicopter door gunner in Vietnam who later worked in the garment center and can still spot a tailor-made suit by the sleeve buttons alone. “We live in a life of double standards. We have all these great people who go to work, donate to charities, talk about how the war is horrible — but everybody still thinks it’s O.K. to have the Robin Hood mentality.”
