These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Moral Event Horizon: Anti-Villain he might be, but Francis Gibson kidnapping children and using them as leverage is pretty bad. If you can somehow forgive him for that, remember that one of the hostages is his own daughter.
What's worse, he's perfectly willing to let her get roughed up in order to cover up the fact that he's leading the whole thing.
Any possible sympathy you feel for Gibson is destroyed when he executes Jin.
