I don’t know how extreme lockdown advocates — who effectively chose to “divert the trolley” toward these outcomes, while claiming there was nobody down this side of the track — can live with themselves. Even if they did save more lives than they cost, deaths caused by action should be valued higher.
Furthermore, while some restrictions (like closing theatres, nightclubs, bars, restaurants, and restricting large gatherings) undoubtedly saved more lives than they cost, others pursued in the ideology of a “proper lockdown” almost certainly cost more lives than they saved.
Criminalising leaving the front door, international travel restrictions, attempting to put limits on exercise, and closing outdoor venues are among the unforgivable ones; as well as all restrictions where they continued for longer than the immediate period of healthcare overwhelm.
Even something seemingly innocuous like cloth face coverings may cost more lives than they saved, as they have a relatively small effect on viral spread, but deprive someone on the edge of an empathetic smile, increase social isolation, scare people off public transport and onto riskier modes, remind people of a depressing pandemic, make commutes or workplaces slightly less pleasant, make those unable to comply feel like pariahs, etc.
