Speaking of epigenetics, an old man accumulates his faults by recording his experiences in the world since he is young. No one is born old. 壞和慫 are capabilities first in all people before they are manifested in the old men. But it is alongside helping developing this world a man gets old. If everyone dies young, the world may be more pure, but it should be much less developed.
So, Doc, your wisdom doesn't work in this case.
A line of poetry by Rumi:
This world eats men and women.
