The radical fundamentalists will often look for some "sin" on the part of the victims, or their relatives, or society at large to blame it on. Much in the same way that this bozo did.
Many believers are not such ass-hats as this. But their response was and is very similar to what mine once was.
I would quickly dismiss the question and focus on finding the heroes: because after a horrific tragedy, especially one involving man's inhumanity to man, you need to reassure yourself that there still exists such a thing as good. But I also put it out of my mind because my belief system did not permit questioning God, or "His ways" or "His Perfect Will." We would always say that this was a great tragedy and we just didn't understand God's ways but we knew that when the roll got called up yonder in the sweet by and by, we'd understand and fully appreciate why this horrible thing had to happen.
Only later did I realize how twisted this idea really was.
And any time one makes an excuse like this for why the all-powerful, all-knowing, ever-present (and above all: loving) deity didn't show up to prevent a tragedy, they are essentially saying is that the tragedy is part of the divine will.
In other words, the deity wanted it to happen so he/she/it could prove some cosmic point.
Noted creationist William Craig Lane put it more bluntly when he justified the slaughter of children by the Israelites:
"God has the right to give and take life as he sees fit." Translation: "my belief system does not permit me (or you) to question God, or 'His ways' or 'His Perfect Will.'"
"The death of these children meant their salvation." Translation: "the deity wanted it to happen so he/she/it could prove some cosmic point."
And here is where the horrible tragedy gets compounded.
When you see it this way, the deity not only allowed it to happen, but consciously and willfully wanted it to happen.
If the deity consciously and willfully allows a horrible thing to happen because it wants it to happen, the deity is the accessory to the perpetrator. In a court of law, such actions would be a felony.
When viewed through this prism, it is easy to see how so many people become, as I did, completely disillusioned with theism in general, and christianity in particular.
It all boiled down to one question that I could never provide a satisfactory answer for:
If you worship a god who apparently wants senseless tragedies to happen despite being able to prevent them, how can you honestly say that your god is good, or loving?
