"One should open one's eyes and take a new look at cruelty" Friedrich Nietzche
That happens to be the 1st sentence of a book that I just picked up at random here at the library 20 minutes ago. (By at random I mean that I sometimes go through the books in a section where they store books that haven't been refiled yet.) Therefore I felt the "hoo-doo" upon me to go ahead and quote it here...
P.S.- For absolutely no reason, here is a song that I suggest anyone with 4 minutes of time go ahead and listen to. It's a really good song and may even lead to relaxation of pent-up edginess... (Technically the song does contain "an incline"[physics] and "the difference between right and wrong, bad and good"[philosophy tinged].
If the youtube thing doesn't work, so be it...
