Perl may be used for untoward purposes, from spam to porn sites. But it is also used to benefit altruistic endeavors as well--probably more so. But you can't blame the tool. Any tool can be used for good or bad. A gun can be used to commit a crime or stop one. And it can't be legislated--just like morality can't be legislated. The only thing that will change the use from bad to good is a change of heart.

This is in keeping with your last "Give a man...". Responsibility, virtues, character, are the attributes we need to impart to those we have influence over. On a lighter note:
Teach a man to write Perl and fed him for a day. Teach a man to use strict, and feed him for a lifetime.
