Because you said you rewatched it, how do you justify you use of the words "sterilized" and "humanoid" in your comment I originally replied to? Additionally, you use the word "Centuries" but the bomb will only "make the planet uninhabitable to all human life for the next fifty years."

What occupation are these Maqius humans fleeing from?

Why do you say they have no other options despite being offered to be resettled?

How are the Maqius "reclaiming" that world?

Is using a chemical method to make the planet uninhabitable to humans less moral than Picard teleporting everyone away against their will?

What do you think the cardassians would have done to the men women and children if Sisko did not solve this problem preemptively?

Edit: was it immoral for Kira to burn down the cottage in DS9: Progress?
