Who Died?

Yes, the only reason Aiden threw Adam out of the lab in Dead Lands was because by doing so he was trying to create a new Natural Phantom.

Could an intelligent and cold-blooded free scientist like Aiden just forget the people inside the iron container time after time?

Of course not, it was simply impossible to allow such a thing to happen even once. It only took place at his will and initiative.

According to his statistics, it was obvious that surviving, becoming a Natural Phantom, and returning to the Citadel was unlikely, only 0.3% succeeded, and... Adam became one of them.

Well, that meant that on average, for the birth of one Natural Phantom, Aiden was sent to their deaths 332 young men from the slums who just came to take the test and get some food with credits, just like Adam on the day his whole life changed.

For Aiden, this was acceptable collateral damage.
