How does the interaction between Final Sacrifice and Nonlethal Spell work?


Final Sacrifice (https://2e.aonprd.com/Spells.aspx?ID=689) targets one minion, slains it and does damage to everyone close to it.

Nonlethal Spell (https://2e.aonprd.com/Feats.aspx?ID=1835) can make a spell nonlethal, which means it "knock creatures unconscious instead of kill them".

What would happen to my minion if i cast a nonlethal final sacrifice on it? Would it die or not?
