'Good' and 'Bad' are extremely relative based on your experience which keeps changing. What looked good yesterday looks bad today. what looks bad yesterday seems to be better today.
Good and Bad are our experiences. Those experiences that give us satisfaction we call them good. Those experiences that give us dis-satisfaction we call them bad. For a serial rapist, raping gives him/her satisfaction. It is good for him/her.
Often our satisfying experience may have a negative impact on the overall evolution of the society. We switch on air-conditioner at home. It is good for us, gives us satisfying experience. But it is bad for the overall society's evolution, as we are polluting the air that is common to everyone.
So what does dharma do..?
Those that are against sustainably evolving the society, dharma (the laws of universe) eliminates them. For eg., it brings in an awareness to people on the side-effects of ACs. Now we may still ignore and keep using it. It brings in more global warming to make inhabitation tough. We may still ignore it. It will create a huge man vs animal/microbes fight where in human beings get destroyed and planet is safe. Let's say we still win over it. It destroys the planet's life completely so that things can start fresh again. This is just my imagination, but could be real.
For eg., if a person becomes too ambitious such that the society gets driven by his/her wills and fancies alone and not by collective intelligence (which is the way to sustainably evolve the society), then dharma creates a lot of opposition for him/her automatically and overwhelms him/her. But let''s say for some reason the opposition to that person is totally eliminated or they cannot overcome the person, then dharma destroys the whole society, as the society cannot sustainably evolve. There are umpteen number of examples in the world and many more will come.
Brahman in my understanding is expansion and evolution. Saguna brahman is this evolving universe in which matter and beings manifest whose hallmark is the preponderance of some guna over other, giving them an aham-kAra, a distinct identity, when they interact with other matter and beings. The ultimate dharma here is to keep evolving sustainably into higher and higher forms of intellect. The fixed laws of Universe, which we perceive as dharma, are manifestations of that sustainable evolution. Whatever sustainably evolves progresses, else perishes.
So at times what we say as 'good' may be against sustainable evolution, against the dharma. At times what we say as 'bad' may be for sustainable evolution. It is tough to find them relating at a personal level. We have to become impersonal, think from a different plane shedding a lot of aham-kAra (which is tough) to figure out what is sustainable and what is not.
