No, of course not, at least not under the vast majority of circumstances. But I don't think we need to choose between villification and lionization here. What happened was bad, and a shame, and his family is left with a burden for a legacy. You're right about all that.
But *obviously* severely depressed people are not thinking rationally, and don't make the ethical choice in their right mind. Grief unchecked can become very intense, almost like a protracted physical pain, like being on fire. Thinking can become like the delerium of someone who has been running a high fever for a long time.
You should be careful how you judge such things, lest you have occasion to learn better by experience. None of us knows the details, and that's where "the devil is," I'm told.
People who are turbulently depressed should seek help, either medically or otherwise.
