It is enough to search for the etymology of the word nice to realize that it is not the most healthiest attribute to embody:
nice: Middle English (in the sense ‘stupid’): from Old French, from Latin nescius ‘ignorant’, from nescire ‘not know’.
This leads to an odd dilemma if being nice literally means ignorant or stupid. Should you be bad?
That it is a false dichotomy an assumption that the only two options are either nice or bad. As far as I know they are both vices, if nice people are ignorant which means to be willingly uneducated and irresponsible even when information is available to you, while bad means being corrupted, not being able to differentiate between good and evil and justify your evil actions as natural or normal unavoidable part of life.
Both are destructive and self-destructive life philosophies and behaviors, that will not only cause you a lot of sufferance but it also going to affect the people around you.
Virtue is the point between deficency and excess, we could consider being nice the vice that is going to create deficency in someones life and bad or corrupted the vice that is going to lead to excess.
The virtue between these two vices is righteousness, it is the attribute that makes one particularly preoccupied with treating other people in a fair way, and expecting that others are going to reciprocate.
Being righteous makes you a little bit more difficult to be around, because you are going to inconvenient other people whenever it is justify.
Being difficult it just means that you are hard to please, because you now have a quality standard, there is a very justify reason why we find attractive people who are willing to walk away from potential relationships or are not afraid to say no. It indicates that you are a high quality person, and that the relationship with you is going to be one of a higher quality, because you are going to maintain that standards.
There is one pitfall you can fall into whenever you are preoccupied with righteousness, that is to become self righteous. Which is the believe that you are always right and a victim, which is an express way to become corrupted.
This is why righteousness needs to be balanced by humility, which is the realization that you are not perfect and you are very susceptible to mistakes ass well. Which means that even when you make your priority to treat other people fair you are not always going to live to those expectations.
