I've done this once in the quite literally thousands of hours I've been playing this beautiful game and I immediately felt dirty for it. Normal people will stumble on this *feature/exploit* , feel terrible and stop doing it immediately. Psychopaths will do it and continue to do it regardless which really is sad for them. Its not their fault though, you have to remember that its a genetic flaw in their brains chemical make up that sets them apart from the rest of us. They will never know love, only boredom and indifference.

I have no reason to, honour, integrity, all those fun things, but if you don't then by all means. The other side is they could've let themselves die too, but kept trying, in their position I'd want to deny the farmer if at all possible the chance to farm.
