I. Am. Not. Comparing. Him. To. Hitler.
Is that clear?
I was establishing your thoughts on the principle. We'd all kill Hitler in 1930, no questions asked. But there'll be a line somewhere, where the good that's done by the death doesn't materially outweigh the killing of the person, particularly of they're not *directly* at fault. Would I kill Boris in 2019? Yeah I would - his decisions led to thousands additional excess deaths.
If Biden stays on the ticket, then Trump wins the presidency. That is catastrophic for global security, particularly in the Middle East, and for the people of Ukraine. It's more than feasible that tens of thousands more people will die.
So yeah, if a health event gets us an electable Democrat, then I'd happily grease the steps for the greater good.
