when does a preper become a raider

[Reality Jones]

Here's the scenario.
It's been several months since TSHTF and the generator you have been using for power has run low on oil and wont start, for some reason you forgot to put it on your list of things to get and as a result you now have a situation on yr hands that means you will have to obtain some more.
You are still trying to avoid the cities and towns and you know that there is an old scrap yard a mile or so down the road from yr BOL that appears abandoned.
you get to the scrap yard and after watching it for several hours you see no sign of occupation and so decide to 'scavenge' what you can. You find a knackered looking lawn mower and decide to extract the oil from that, half way through filling up your can you hear a noise behind you. You turn around and there's a hungry looking man with a shotgun, the shotgun is pointed at you.
What are you now? A scavenger or a raider?
