I am quite confident that she could benefit significantly from somewhat liberating herself from the "all conflict, all the time" mentality that she has been raised to.
I'd argue that the conflict focus is not so much a problem as the over focus on violent conflicts. After all, the idea of conflict driving progress has solid backing and is generally true. However, it's also worth noting that not all conflicts involve violence. Even setting aside the more grey area of sports (or the less scientific entertainment industries like idols/bands, actors, authors, etc.), there's the basic principles of free market, wherein conflict arises between various parties over materials, marketing, target demographics, buyers, etc. With all kinds of complex relationships to consider regarding traits like manufacturing cost & time, distribution, creating interest in the product, convincing people it's more worthwhile than other products, etc.
Even without a specific competing group, there can generally be "conflict" with one's circumstances as finite resources need to be efficiently used to accomplish goals. Or, in really any category there's the potential for amicable competition and rivalry fueled conflicts, where none of the involved parties want to see the other fail, but rather attempt to use each other as measuring sticks to encourage a constant trend of self improvement in a given area as they seek to outdo each other.
Point is, there's plenty of conflict she could be focusing on that doesn't involve weapons or death. Whether she'll actually shift to focusing on that is uncertain, but it's a potential option.
