How many people lived?
What were the circumstances that led to these deaths? If the bible is the source for these figures, and they are deemed accurate. Then the bible's justification of these deaths must also be deemed accurate.
Skipping the bible stories, the same logic can be applied to childhood diseases and chronic debilitating illnesses. If these conditions are rare, and the good far exceeds the evil, then the judgment that the theorhetical creator of the rare conditions is evil is not justified.
So you accept that the Abrahamic god kills. If you read the bible you will see those claimed to be killed were not "gods chosen people". Being omni everything, he made them to kill.
Have you ever seen someone die of leukemia? Trust me there is no good in that. Creating such illness can only be evil. And excusing it, i am not going to comment
