His hidden power is plot armor. Something bad happens, oh wait no it's fine. He want's to die sOoOoOO bad but he doesn't want to do it. Just keeps droning on and on about it like a broken record. A manga with a bunch of flip flopping characters, meh.

Probably the selfishness and determination to go through with it. The little lady couldn’t bring herself to do it when she heard Gomes’ plans.

I thought the same.
Page 25 looked a bit strange with ellipses leading to a chuckle. A conceding/relief sigh would also fit the page's context and a cynical character archetype. But the chuckles in the story so far gives off the impression of him being more of a cynical oddity and it works. I can't tell whether it's correct or a TL mistake.
I'll still assume they're chuckles given the way it's written.
*Editing my shitty grammar
There are some text bubbles that are obviously chuckling in previous chapters. Sighing is unlikely.
