haha well i disagree, id put it this way. Bacteria have 1 dimensional thinking, solely on reproduction and eating. Animals have 2d thinking, since they also think about things like love and compassion. Humans have 3d thinking, meaning we have total free will in terms of thinking. We are not slaves to our nature, obviuosly there are things we must do physically but mentally we can do whatever we want. Some decide to release sexual energy through rape, most through mutually agreed upon sex, others by fapping. We can take care of our needs however we want to. We also can do things like sacrificing ourselves for others. Your point is wrong when you consider those who work at goodwill for instance. Many say they do it to seem nice but truly those who do these things do it just to help others, no selfish desires involved.
