This is good enough for me, but going further... The Gospel of Jesus Christ, and Ahimsa are persuasive for many.

EDIT: just had a shower, and remembered this paper that supports the idea that violence is an inter-generational disease:

Abstract

> I study the role of the monopoly of force in shaping cultural traits associated with violence and their persistence. I do so in the context of the settlement of the Canadian Prairies from 1890 to 1920. I find that places with a weaker monopoly of force by the Canadian state during the settlement – as measured by their distance to the early Mounties’ fort – were and are still more violent despite the later consolidation of the Canadian state. My interpretation is that counties with a weak monopoly of force during the settlement developed a persistent culture of violence. Consistent with my view, I find that hockey players born in these places behave more violently even when observed in a common environment: the same team in the National Hockey League. Besides the persistence of culture via inter-generational transmission and socialization, I find that culture favors complementary institutions and political views, creating an additional channel of persistence. Finally, I show that the monopoly of force during the settlement crowds out pre-existing cultures of violence brought by immigrants. Despite the persistence of culture and its dependence on past circumstances, the right institutional conditions can change it
