Think about how many people have sacrificed themselves for others. Not just jail time, but death. Would each of those people have lived completely pure, selfless lives if they hadn't done what they did? Probably not. Who knows, some might have ended up being anti-maskers. It is said that "dying is easy". Making one clearly right choice, damn the extreme consequences, is actually very normal for humans. Just as normal as spending a whole life making bad decisions. Even more bizarre is the two "modes" aren't even mutually exclusive.

Page 5, new hospitalizations, 7 day numbers per 100K people in each group June 2022 unvaxxed 1.4/100K vaxxed unfinished 1.3/100K vaxxed 2 doses 0.5/100K vaxxed with booster 1.7/100K
To be fair most of these people are hospitalized for other reason than COVID regardless their vaccination as was always the case even when they were spreading propaganda about hospitalized unvaxxed. Numbers in ICU look better for vaxxed, but there are way too many factors to consider, you are more likely to have better life style as vaxxed risk group than unvaxxed risk group, which doesn't really say vaccination works.
So yeah, masks work in theory, but reality shown us they are completely useless, especially with newer more infectious variants. If they were such great invention we would not have flu and other respiratory viruses, in the end everyone will get infected anyway.
And during the pandemic, a lot of countries did indeed not have their usual flu season.
