From some of the calls I have listened to(engines failing, landing gears failing, close calls, etc...), it is incredible how composed the parties involved are! As much as some people point the finger at one person in the situation, the important thing is that these incidents are an opportunity to learn, and that is something the aviation industry seems to do very well.
If you don’t stay composed you’re pretty much fired.
It’s likely part of their training. Adding personal commentary to comms during a tense situation only increases the likelihood of a bad outcome.
The ATC almost never does that, but I've certainly heard the pilots say it - or even other pilots comment on it.
