> When talking about farm help, they may hold a grudge against the animals they are working with. A friend would work his uncle's farm every saturday to help clean up after the pigs. His job was basically shoveling pig poop for 8 hours (or other equally not-fun jobs). It would take a day before he smelled normal again. Doing this kind of work can make some people resentful of the animals they work with.
Working in a call center, I resented every customer I dealt with. At no point did I electrocute, scald, maim or torture them. Not just because of the distance, but because I'm not a fucking psychopath. People who abuse living creatures do not need any defense; on the contrary, they're immoral, depraved and indefensible.
