The universe doesn’t care about you. It is indifferent to your suffering and unmoved by your tears. It is a completely impersonal system of causes and conditions.
Because I don’t believe in a supreme being, I don’t have a problem with evil in the natural world. This kind of evil is not a problem, it is a part of the natural system.
This means we can deal with the evil we can control, I am speaking of moral evil. Moral evil refers to the unjust harm that is intentionally done by humans to other sentient beings. This evil we can stop by law, by example, by societal pressure, and by education and training.
Evil is caused by humans. Humans are not all-good. They are a mixture of good and bad. Governments and cultures should be so designed as to produce the highest good of all while protecting the rights of each.
