Of course people know bad things are coming.
Over the course of a 15 year career, I’ve responded to six hurricanes, and one earthquake. Haiti, Katrina, Maria, Michael, Florence, Dorian. Each response left me with something that will never leave my brain. Haiti above all. The saving grace is that I’ve been able to spread those moments out across 15 years, with gaps in between.
You’re asking medical workers to live disaster response day, after day, after day, for an untold amount of time. To use your analogy: it’s asking a LEO to shoot someone in the line of duty every day, and telling them it’s just part of their job. It’s an astonishing lack of compassion.
@Abe has “First Do No Harm.”
@MoseyingAlong has a vocation that stretches back as far as humans. I have “Honor, Respect, Devotion to Duty.” I’m not exactly certain what you have, beyond stories that don’t even involve your own suffering.
