Now this is just an anecdote and probably exaggerated, but if you're ever on your feet wanting to scream at someone at work then that is a serious problem that you should definitely look into.
If you haven’t felt that way you probably never let yourself experience deep passion for your work. To each his own, but I find that it requires passion to do remarkable things. There is no shame in punching the clock for your 401k.
I'm delighted by how passionate people get.
But that doesn't make it okay to yell at people over their code.
It's a fallacy to imply that this emotion is a kind of passion in the sense of passion for one's work. They are at best somewhat corollary, in that emotionally unstable people might be more statistically likely to have passion for their work.
Any more factual descriptions of the story? What were the "bad changes"? Done by whom? Why wouldn't the CTO check the source code themselves?
