Why Did We Get Worst Of Both Options?

During the Covid pandemic, something we heard repeatedly was we couldn't continue to lock down the country as it would have an adverse effect on the economy so it became a toss up between a higher death rate or a saved economy and the Government went with saving the finances of the nation by being one of the very first to throw off the protective blanket and open up the country again.
As expected, part A happened and the infection and death rate rose but somehow part B never so how did we get the worst of both worlds, one of the worst death rates and the economy still going all wrong?
The UK sits uncomfortably towards the top of the Worldwide deaths league table with 177,977 but the Organization for Economic Co-operation and Development (OCED) have announced the UK as the worst performing economy of all the major economies so what happened?
As the pandemic was global, our high death rate can only be down to the Government decision making which we know was dangerously faulty from the start but as the financial fallout is also global, why are we seeing a 9.9% slump, the biggest contraction since 1709, while the decline at the other major economies in the G7 was 3.5% in the US, 5% in Germany and Canada, 5.6% in Japan, 8.3% in France and 8.9% in Italy.
The chancellor, Rishi Sunak, tried to explain it away by saying it was down to the pandemic but that wasn't only the UK, the rest of the G7 suffered it as well.
As 10 Downing Street was the most Covid law breaking place in the nation we can see just how come the Coronavirus response turned out to be such a shitshow and resulted in such a shocking death toll but the financial crash must be down to good old fashioned political incompetence.
