This isn't the hypothetical where you're stealing a loaf of bread from the market to feed your starving family. I certainly respect that taking the moral high ground isn't always easy and that some people are going to be in situations where it is more difficult for them to do so than for others.

But the standard for acting like an asshole has to be greater than simple expediency. The necessity of breaking the social contract has to be roughly proportional to the community inconvenience; that's why firemen get to use the siren and everyone is supposed to yield when they are headed to, well, fight a fire, but I don't get to use one when I'm headed to the grocery store.

If I bang on a stranger's door at 6am because their house is on fire and I'm trying to warn them, then that's great, because the "don't harass strangers at six in the freaking morning" social norm is less important than the "OMG THE FLAMES THEY BURN!" social norm. In contrast, if I bang on someone's door at 6am trying to sell Amway products, then I'm an asshole. Finally, If I bang on someone's door at 6am, insist that their buddy, whose name I found by going through the trash, has photos to share with them, and only later reveal that there never were any photos, then I'm an unbelievable jackass.
