Reply #4: It is very rational to oppress

[angrycarpenter]

Empathy is an emotion that seems to escape them. If you were in a life boat and there was a sick person on board who would eventually die, the rational thing to do would be to kill them and throw them over board. It would save food and water and the sickness will not spread to the rest of you. But most people would not do such a thing. Rational does not mean right in all cases.
