No, of course not. Our previous President not having taken more decisive action on the COVID pandemic doesn't make 400,000 people any less dead.
But this is, in my opinion, more a tragedy of circumstance than anything else, and that's what our court systems should be working to mediate. This guy, with a strict halfway-house counselling & treatment program, could be solving mathematical problems at a top 10 university right now. Instead, he's locked up in prison for the foreseeable future — what good does that do for the two dead people, for society, or for him?
Prisons should be there to house people who can't be rehabilitated, and to punish those who've done things seriously wrong (which may include him, but I would err to think not).
