Another way of looking at it is that all things eventually turn into other things.
At what point does a thing seem to end?
At what point does its goodness seem to leave it?
What made it seem to be good?
Or did it ever have any goodness?
Did it just have being?
Is being not good?
If a thing can go from good to bad, can it not go from bad to good?
Who decides whether it is bad or good?
