I disagree. If society always let people get away with their crimes, criminals would gain an evolutionary upper hand and soon crime and distrust would become the norm. Criminals would be popping out children and altruistic people would be picking up the bill.

Also I think that our current system lets white collar criminals off too easily; they should be punished more severely.

This type of evolution is especially dangerous in a modern context because technology and globalization have taken the humanity out of our daily interactions and have therefore reduced the importance of altruism.
