Why was dropping the bomb on japan bad?

Dropping the atomic bombs on Japan in 1945 caused immense civilian casualties and suffering, leading to the deaths of approximately 200,000 people, many of whom were innocent civilians. The long-term effects included severe radiation sickness and lasting health issues for survivors. Additionally, the bombings have sparked ethical debates about the justification of using such devastating weapons and their implications for future warfare and international relations. Critics argue that alternative methods could have been pursued to end the war without resorting to nuclear violence.
