There are three types of people in the world: Trey Parker and Matt Stone describe them here (WARNING! NOT SAFE FOR WORK!). But I think there’s a more straightforward way of describing those three types of people:

“Most of the people in our society are sheep. They are kind, gentle, productive creatures who can only hurt one another by accident.
“...Then there are the wolves, and the wolves feed on the sheep without mercy.
“...Then there are sheepdogs, and I’m a sheepdog. I live to protect the flock and confront the wolf.”

Just like Sam does to Ralph. Go Ye and read the rest. The Macker Commands It!
