Which I believe is in contrast with the older games. Haven't played them but from what I've heard he'd pursue conflicts because he enjoyed them. I think this change is because of his ongoing process of coming to terms with being a father which takes the act of killing and twists it inside out.
I may have missed or forgotten the explanation behind that though. I suppose he was always stuck in the safe area around their house?
That aside, the new God of War games are great, and the whole franchise is a good example of how they took a fairly straightforward character - savage, angery fellow - and evolved his story and character over a long span of time, subverting itself etc.
(The Valhalla DLC is where Kratos goes to therapy lolol)
"Don't go there - there are mines there" is what my mother would say occasionally back when we were living in Kuwait in the mid 90s.
I guess it's a similar situation.
