The point of the passage is humility and judging, not stoning.
We all must pay the price, proportionately, for what we’ve done wrong.
I hope not. We all deserve to go to hell, no matter the sin. You and I and Tiger are all in the same boat. I would hope that none of us will pay that price.
Baloney it is. I’ve read the Bible many times over, and Jesus felt that the proposed “punishment” was excessive. If your interpretation was true, then I’d be free from speeding tickets, since all law enforcers speed too.
