It would depend on how long this revenant phenomenon has been around. If it has been that way since prehistoric times, humanity and civilization would have evolved quite differently. Ancient cultures started as hunter-gatherer societies and were much more community-focused. There would be strong cultural practices surrounding
1. Making sure everyone knows how it works, at least as well as is understood. No doubt it would become an important part of early proto-religions.
2. Dispute resolution. Some form of community support and a relatively universal understanding of justice. It could be violent, like blood money, although early cultures didn't have money per se so something else would have to be worked out. I would prefer more non-violent solutions. Community therapists of some sort: many early cultures had wise men, shamans, matchmakers, and various other important social roles. There would be someone whose role is to settle disputes and ensure fidelity and harmony. People would mostly be willing to take part because everyone understands the consequences of not doing so, and it is something that they strongly believe in due to their religion. And in this case, it's based on actual real consequences, not just faith (although depending on how successful they are, it would still happen perhaps once every average lifetime of an individual since the younger generation has never seen it before).
3. Forgiveness is an important part of the culture and religion, managing one's emotions is taught from a young age, like in many Buddhist societies. 917
Meditation, controlled breathing, the taming of the passions, self-control. Like the Jedis, if you like.
I'm basically envisioning Native American society + Buddhism. Warfare would consequently be very uncommon, people would literally be forced to negotiate and practice diplomacy. Society would likely develop either more slowly or much more quickly, it's a bit up to your imagination. In a larger society, it is harder to maintain social cohesion, but maybe their peacemaking skills would actually lead to a more utopic type of society. There would still be risk to manage, but the religious aspect likely would be more dominant. Consider this: people wouldn't fight over whose religion is correct because everyone comes back from the dead no matter which religion they believe. Therefore I would assume there is not a lot of structure to the religion (such as in Buddhism) as to specific interpretations, perhaps it is more Deistic, this allows it to be more universal. I still predict a lower density of the population. Note that people will pretty much be guaranteed to believe in a spirit of some sort, and life after death (perhaps reincarnation?).
From this perspective, if it's something that has always been this way, then start with how you think society would have organized in early times and try to imagine how it would evolve forward. If you want organized large scale agrarian/industrial societies to exist, then think about how society managed to get that way without people getting killed.
This assumes that the risk of the revenants can't be managed by some means, such as cremation or prevention in some way as others have suggested. This then largely depends on the details of how you want it to work. If it's unavoidable for the most part, then society would be forced to evolve harmoniously or else remain as relatively small communities. If it's able to be managed and avoided, then perhaps people develop more selfish tendencies over time as the risk becomes lower. Even so, the mere fact that people literally come back from the dead due to their willpower is pretty incredible and will have a huge influence on people's understanding of the universe and metaphysics, and it will play a central role in any religion. 164
