I see no difference between the Jainism’s policy in self defense/justified violence and any other religion in comparison, therefore, the discrepancy is not a result of Jainism being a more benign religion, but rather a result of external factors. For example, if Jainism was a more ‘popular’ religion, you would see something on the news now and then. The lack of violent example in this case is then perhaps due to their smaller number, relatively speaking. That being said, it is an observed occurrence when a group is small relative to its neighboring groups, that group must “behave and more strictly monitor” itself. Bigger groups have more power, more control, and therefore dares to corrupt. I think this is also true to nations. When a nation starts, it may adhere to its founding principles and contract, when it grows large and powerful enough, it will corrupt.
