Yes. It had a short term impact, is still in memory and not my first. I knew this guy, not closely but saw him frequently. His last act was desperation to get outside as he might be seen (and was), his phone was dead. I rationalize it was the time before they came and got me. Somebody should have started doing something other than screaming for help. Do something, even if it is wrong. I rationalize, I never had a shot. I rationalize his lungs were shot, other organs were effected, and apparently they were, so I never had a shot. Still, failure to achieve goals in more impactful when it is life or death, the checking for pules, positioning the victim, ensuring airway is open and the look in the eyes as you give 3 rescue breaths before normal CPR. I'm philosophical, though when necessary (and it has been) can be quite cold, but after the emergency or circumstance, action, whatever, some things you remember. For him and this event, it is the WTF? look from inches away eye to eye.
As for saying people were dropping like flies in Detroit, it is just a figure of speech, a self-protection mechanism, as I have no intention to bleed for everybody everywhere that died in that pandemic, at large. I will do what I can, when I can, if I can, if it is right in front of me. The rest is God's problem.
