We've already had social commentary like throughout this. Mostly about, "What is a human and what is a monster?"
If anything I feel like Lewis is the most "human" outside of the kids, because while they were still food he respected them as more than just "cattle".
well it doesn't help that when people die, like pedro,pound, vergo, or monet, people still don't believe they are dead so they don't count XD
personally i don't need death to consider it a loss, but that's just me
Those all occurred after Ace and Whitebeard, so those are all more likely official deaths, since at this point Oda HAS killed people. We can never be sure again.
