The mortality is affected only in as much as you avoided the much worse mortality rate for the no ICU capacity scenario. This is what we saw in Wuhan and now in Italy. The difference seems to be something like 5x higher mortality or so (1% => 5%).

All of us getting sick in an orderly fashion has a huge benefit even if it turns out that’s the best we can do. But perhaps we flatten the curve for long enough we buy time for treatments to come online and to get closer to a vaccine.
