>there is no rational or reasonable explanation
Marxist brainwashing and retarded Marxist belief that paradise will start as soon as they destroyed everything + killed the "Nazis".
>sacrifice kids, so elderly can live
the corona motto was "if this saves a single life (including children with pre-existing conditions), it's worth the sacrifice"
of course that was not true, but that's not the point.
The actual point comes when you notice that there was recorded excess mortality (fake or real, it doesn't matter) and the same people who said the former now ignored it.
But even that makes sense. Some people simply consider most other people a "burden" for this "planet" and want to get rid of them.
