Is there a difference between 爆発しないといい and 爆発しないとよくなる?


I'm having a hard time understanding how と works with negative verbs. With
positive verbs, it is easy to see the timeframe of いい because it occurs after
the verb happens, but if the verb ends in ない, how do I know when いい happens
when a verb ending in ない means nothing occurs? I only seem to have this
problem with いい and not だめ. For example, 食べないとダメ means that if you don't eat,
you will eventually have something bad to happen. If reworded as 食べないとだめになる,
the sentence still makes sense because the original sentence also reflected a
change in state. However, in a sentence like 電池が爆発しないといい, 爆発しないとよくなる seems to
have a different meaning.




First of all, "食べないとダメ" means "you have to eat," not meaning "食べないとだめになる."

In this topic's context, "いい" is used when you describe your hope or wish. For
example, "爆発しないといいな" means "I hope it won't explode."
