Someone once told me that even though they ate meat, they felt mean killing lice. Not I. Apart from legal concerns, I'd pretty much feel significantly worst killing an animal than a person (Except if it was trying to hurt my kids. Nobody fucks with my kids). But lice are where I draw the line when it comes to animal preservation, my one exception. I have no qualms about exterminating the little fuckers. Seriously, they deserve to die. Parasites contributing nothing positive to society. A bit like the Liberal Party really.
