Answer:
It is important to live a moral life if you'd want a personal relationship, because a person's morality can benefit us in some way. Moral traits have social value and signal to us whether we should approach or avoid and whether we should affiliate with that person. An example a moral life is always telling the truth, keeping your promises, and another is to treat your partner how you'd like to be treated. My thought on living in a moral life is a bit frustrating, but fair because you wouldn't like it if your partner, or anyone in general were to break their promises or even lie to you, whether if it's constant or not. Anyone would be upset if someone lied to them, but I think it's fair because I'd appreciate it if my partner or anyone would tell me the truth at all times, and they'd appreciate it if I did the same to them.
I hope this helped you!
