In Jainism, non-violence (ahimsa) is the highest principle and is kept as long as possible. Deliberate violence is typically not celebrated in Jain scriptures or major ethical tales. When violence does appear in Jain narratives, it is usually shown as a transgression to be avoided, a situation of extreme necessity (often in self-defense or to protect others), or as a result of mistaken judgment that leads to repentance and correction.

So, there isn’t a standard Jain story that positions ahimsa as “held at a high level for a long time and then deliberately used violence” as a normal or accepted turn of events. If you have a specific text or tale in mind, tell me the title or passage and I can explain its exact rendering (including how Digambar and Shwetambar traditions might differ in that episode).

Note: In all cases, Jain sources emphasize that any violence is a serious lapse and should be understood within a context of moral restraint, with focus on repentance and seeking upliftment.
