Johnson wasn't PM until a couple of months ago. His cabinet weren't the ones that shat on the NHS. He listened to his own nation's medical advisors, which as per your original point were put into position by the previous administration. His political advisor is a cnut, but that doesn't mean he himself deserves to die for it.
So far HIS administration has;
Listened to government advisors
Change tactic when it turned out the information was false
Put economic policies in place to protect millions of people in the UK
You keep saying "they" as if they = Boris. If Cummings was the one in ICU, or Osborne or Lansley, Hunt or Cameron I would give less of a shit than I do about Boris, which is already very little to begin with. But that's all irrelevant. Proclaiming that you want someone to suffer because they've made other people suffer makes you just as much of a cnut* as they are. Perhaps even moreso because they can at least try and hide behind a sense of ignorance to the situation.
*Not calling you specifically a cnut, I'm making a general statement**
