Intelligence imo is just a multiplier for one's influence on their surroundings. It doesn't make a person "good" or "bad", it just increases the power of the person to influence the world, especially in our current society.<br><br>As for happiness, that is more determained on a person's temperament. Some people can be happy with almost nothing, and others can never be happy even when they have more than almost everybody else. Even if a person would have unlimited influence on the outside world, and would be able to shape it exactly like he would want it to be, he still would be dependent on his inside world for happiness, and for some people nothing would ever be good, exciting or special enough. <br><br>Intelligence gives freedoms, but freedom can be scary, no god, no special leader that knows everything and is so much smarter than you, that he will be able to take away all your fears and make life feel safe and certain and take care of your emotional needs. The most intelligent person in the world, would be the most lonely and responsible pwrson in the world, for he could have the most positive impact for the people he loves.<br><br>Pure rational understanding of reality as a organic species that has emotions and eventually dies, suffers, can get ill, has no control over others they love and might lose, just comes with suffering. <br>Even knowing everything might not change that, it might actually take away parts of the enjoyment of living. We all need challenges after all to feel alive. We need the downs to enjoy the ups, we need some discomforts to enjoy the comforts. An almighty person would likely be bored, feel misunderstood and alone and be unhappy still and become unhealthy mentally and than physically and perhaps even a "bad" person eventually.
