'Why is it that people who worry the most about mankind have the least concern for any actual human being?'  -Ayn Rand

I read an excerpt from "Not With a Bang But With a Whimper" by Theodore Dalrymple.  He writes of a British man who was convicted of assaulting or raping 15 women before being released and murdering Naomi Bryant.

Forgiveness is overrated.  Case in point:  An Arkansas woman forgave and even befriended her mother's killer.  He then killed her.

“There are pleasures, no doubt, to be had in crying in the wilderness, in being a man who thinks he has seen farther and more keenly than others, but they grow fewer with time. The wilderness has lost its charms for me.” -Theodore Dalrymple
