Step-by-step explanation:
Comparison of adjectives differs between regular and irregular adjectives. Compaison of irregular adjectives, such as the case here, needs to be memorised:
much and many have the same degrees of comparison; comparative is MORE and superlative is THE MOST.
Levels of comparison for adjective good are BETTER and THE BEST.
Levels of comparison of adjective bad are WORSE and THE WORST.
Note that the superlative form is written with THE.
