While God is not responsible for the gift of freewill, why would he give it to humans, if he could foresee the ultimate fate of humanity (e.g. wars, genocide, murder, etc.)? In response, a couple of observations can be made:
First, this statement is self-defeating. It is self-defeating to say that we do not want our freewill, because we exercise our freewill in claiming this.
Second, if God insulated humanity from evil, this would also insulate us from the greatest conceivable good. To illustrate this, consider raising a child, who was getting bullied at school. If you’ve ever tried to help a child in this situation, you know how heart wrenching this can be! But, how many of us would consider giving the child a lobotomy to solve his suffering? Imagine it. If you lobotomized the child, he would never feel the pain and anguish of being bullied at school. In his lobotomized stupor, he wouldn’t feel the sting of insults or the heartache of maltreatment.
However, while this solution would surely insulate the child from suffering, it would also shelter him from the great joys of life, as well. The child would never experience the pain of insults, but he also would never experience the joy of friendship. He would never experience heartache, but he would also never experience the joy of falling in love. Here lies the point: No one envies a lobotomized person, precisely because our freedom is so important to us. Of course, our freedom allows the lowest of lows, but it also offers us the highest of highs.
Consider another example. If you are a parent, you know that some of your children’s sexual experiences could possibly be aberrant or even abusive. Would you pay to have your children’s genitals removed to protect them from this pain? Hopefully not! In protecting them from pain, you would also be barricading them from genuine pleasure and sexual intimacy. In the same way, God does not want to strip us of freewill, because this would stop us from freely choosing a relationship with him, which is an ultimate good. While God is powerful enough to stomp out free-will, he may not desire to do this, because freedom allows us the ability to encounter an even greater good.
