When it comes to the problem of evil, there has been a trade-off. Precisely because God is good, he wanted to share his happiness with others. So he created humans with the kind of freedom and the kind of nature that would allow them to grow in goodness, deepening their happiness and their friendship with God. Since happiness depends on goodness,5 man had freedom to choose the good, but this same freedom also allowed him to choose the bad. This is called moral freedom.6 Put simply, something good made something bad possible (though not inevitable).
