While I think that ultimately they were 1000% responsible for the loss of one of their students, I wouldn't be overly judgmental. While in Boot camp, the first couple days, there is a bit of shock and awe...some folks just don't handle it very well. We had guys dropping out, passing out, and going into seizures. Some people have trouble with sudden changes to their environment, and this can effect their physical well being as well as the mental.
I have always wanted to do the long course at BOSS, but the cost is an issue for me, unless I hit the lotto.
