if you want signs look all around at how people act man.
and then if you want an idea of what the under-belly of the world looks like go scroll through sites like
www.censor.com and
www.theync.com, the ync is a horrible example of how people get off on rape and murder etc, I would recommend not watching anything that's on there, the user comments alone are repulsive and make anything said or posted in slap look like souped-up bazooka joe cartoons.
if you wanna see amazing shit go to 2leep.com
