is it not the opposite, because as entropy decreases everything becomes stable and ordered?(as far as I know)

Well... dead planets (that harbor no life) are lower entropy than living planets as their surfaces change much less over time. Fewer possible microstates = low entropy.

Hence, if you take a complex biochemical system and reduce it to <100 piles of atoms of specific elements, this is a lower entropy state. Mass extinctions, collapse of civilizations, that does lead to a 'more stable and ordered' state.

Disorder is desirable. Let chaos reign!
