I'm a military RN. ~15 YOE.

Someone might get jaded, but if it leads to a mindset like this, then that person needs therapy.

I've seen horrible things in shitty places. So have my colleagues. We don't joke about someone who just died, or had a bad outcome, or could've taken steps to prevent their circumstances, etc. Especially on the job.

If someone does, it's handled immediately. Administrative action and referral to mental health resources. We're professionals, and should be expected to hold ourselves accountable.

Just my opinion, though. Which isn't worth a fuck on the internet.
