A half-wit's Dark Passenger T-Shirt

I tried to go as "dark passenger" as I could and still bring it back to being just plain stupid. I see it as some guy that's fixated on hitting baby ducks with claw hammers and then when he realises he's said too much- he turns it into "if it were for a good cause." I mean - only if it would rid the world of something horrible, because I don't think about hurting small animals unless it's to rid the world of breast cancer or tourette's or something... I see the guy as not actually having hurt an animal and probably being incapable of it, because he's not smart enough to catch a baby duck. So, basically his dark passenger makes him tell on himself for what he thinks he would like to do.
