No matter what you get, there is a price to be paid—there's no such thing as a free lunch might be the only truth. Everything requires something else in exchange.
And in order to get the purifier from Lin Jie's hands, the only chip she had for trading was a person, a person's life!
It was probably the most guilt-ridden thing she'd done in her life, tantamount to sacrificing a living person so that others could survive!
It was as if she had personally killed an innocent person!
Perhaps others would feel that this was justifiable, nothing to make a fuss about, trading one person's life for the survival of all others was the most correct choice. But what if that person to be sacrificed was your relative?
What if that person was your father? Your mother? Your caring brother or sister? Your obedient younger brother or sister? Your flesh and blood, the closest of kin?
Would you give up your own family for the benefit of all humankind?
