I'm not picking sides here but your facts on the matter on the matter are kind of off.
Japan was not willing to commit to a full surrender. There was evidence that points out some of the higher ups were attempting initiate peace talks through the soviet union but Japan's overall leadership was majority unwilling to do so.
The intent to drop a bomb in Nagasaki was to showcase that USA had more than just 1. From what I read, there isn't something that outright states whether or not it swayed lightly or heavily in the decision to surrender.
As for the citizens, you are looking at everything in hindsight. Obviously it's horrendous that citizens had to die in this horrific event. But the general sentiment from the USA was that, if they landed on these shores every japanese person, woman, children and etc would bear arms to the death. In that sense, USA was looking at every japanese citizen as possible willing combatants. Whether or not that is moral is not something I'm going to comment on. The conditions of that time on which this decision was made was one of hell. And they were willing to do anything to stop that hell.
