Probably because they think they won't get caught. Having things doesn't necessarily mean you also have morals or ethics; it just means you have more to lose.

Probably because they think they won't get caught. Having things doesn't necessarily mean you also have morals or ethics; it just means you have more to lose. Stealing a package might not even be the worst thing they did that day. Maybe they also fired all their company's in-house maintenance staff, and replaced them with contractors that cost half as much, in order to get a one-time bonus of $500. Maybe they pitched a censored and backdoored search engine for China, because Google backed down on that (for now). The world is full of heels.
