It seems to me that the problem in many situations is that suicide is a permanent response to a temporary problem. In most of these cases, were the person being rational, they would probably consider the expected remainder of their life to be more good than bad.
There are certainly exceptions. Terminal illness is an obvious one. A chronic disease - whether physical or mental - that has few prospects for effective treatment is another. I'm inclined to think that Aaron's legal troubles were not, by themselves enough to make suicide a rational option, though I don't know enough about the situation to be sure. If, however, he concluded that his legal troubles were part of conclusive evidence that the world is a bad place that isn't going to get better, suicide might look more rational to me.
