If someone robs a bank, I can understand the motivation: He wants money. If someone punches another, he might want to feel powerful. If someone rapes a woman he wants sex.
And if someones believes that this company stole his money, I can understand his motivations to seek revenge. That does not mean it is right, just or something to look up to. But saying this is completely crazy is a bit naive IMO.
And that is the only arguably victimless crime in your list of 3. A crime can be committed by a rational person (if I don't do this, my child dies), and it can be committed by someone who is not mentally well. I would argue that these, especially the last crime, are all crimes likely to be committed by someone who is not in a stable or healthy state of mind.
Would you say that every crime is either a "rational" crime (if I don't do this, my child dies) or done by someone crazy? If so, I understand the heavy resistance of you and others here.
This is pretty much the definition of crazy, though apparently not self destructive because they survived.
I fully expect the death penalty if he doesn’t prematurely manage to commit suicide though.
