Context matters.
Trump was being contrarian and obstinate about simple things people could do to slow down the spread.
Biden let science about the pandemic take the lead, by and large. But Biden couldn't magically force injections of the very thing that saved the most lives. So people died by the hundreds of thousands, virtually all of them were unvaccinated or under-vaccinated.
Nothing's perfect but Trump let politics get in the way of saving lives. I'll give him some credit, however, for being clear and open about the need for people to get vaccinated later after he was fired.
