" Pure" gas goes bad over a year or more - Ethanol fuel in months

Ethanol NEVER goes bad. Think whiskey. There nothing for it to
turn into... unless you dilute it to the point bacteria can transform
it into vinegar.
Gasoline OTOH is unstable and degenerates rapidly.

Ethanol absorbs water and comes out of solution from the gasoline
(phase separation).
That is PART of it. It is also an "oxygenator" and ethanol blends
oxidize faster than "pure" gas - causing varnish and other deposits in
the fuel system. Yes, ethanol "disolves" varnish too - but it still
leaves a mess.It is particularly bad when it is better than half
saturated with H2O
