Very dark comics.
Logan already living as a farmer who has a family, keeping his head down, and not care of fighting anymore.
He need to get money, which he did. But they killed his family anyway.
Wolverine core value, for being an old cynical man, is that he don't want to care for anyone because he couldn't bear to see them getting hurt.
Logan instinct is to protect, and if he failed to do that, he either get very depressed, or get very violent. And sometimes both.
This is one of those time that he did both.
