Why do Bad things happen to Good people...?

Ok about a week ago I was asked the question "if God is real why do Bad things happen to Good people...?" You know, to understand or even just wrap your mind around this question you have see the difference in coincidence vs. choice. You see God loves us enough to give us "free will" meaning we as humans can obviously do whatever we want whether it's be in love or hate a person, drink and drive, love God or not. Love isn't really love unless you have the option to love. We choose to love God, we choose to go to church and lift our hands in surrender telling the Lord we love him... And that's what makes it such a sweet fragrance to the Lord. We have free will and still choose to love him. But now with that same free will we can choose to make bad "choices" and some times the result of that bad choice hurts not only us but other people as well. Take the story of the man that chooses to drink and drive and while driving he hits the pregnant woman and kills her and her baby. This of course makes God sad but we can't blame God because of the "choice" made by another. We can't thank God for loving us enough to give us this gift of free will, (and yes it is a gift, God could have made us robots) and then begin to doubt God or get angry with him when he doesn't step in and take back the free will once given. It's not fair. When the two parties involved are both human, (meaning like not a fallen coconut from a tree or lighting hitting a tree and making it fall on the road) but rather two humans the outcome of their actions are a result of choices not coincidence. In a sense its "out" of God's hands.
