Off-topic; do you know what percentage of coronavirus deaths had ‘underlying health issues’?
Most every death has an underlying health issue.
Not to be trite.
The real question, glossed over, is would this person still be alive if they hadn’t contracted the virus.
Also known as ‘can I shoot a 90yr old with heart failure’ and not be guilty of murder. I mean hey, he had heart failure, he was going to die anyway. You can’t PROVE the bullet killed him, maybe the shock of being shot gave him a heart attack. He was going to have one anyways...
