From the Jain perspective, killing is not “right,” even if done to save others. Jain Dharma teaches ahimsa as the highest principle, so taking a life is still himsa.

A few important Jain points:

• Intention matters, but it does not make killing righteous.
• Protecting life is noble, but it should be done with the least harm possible.
• For a soldier or householder living in worldly duty, Jainism recognizes that life in the world can involve some violence, but it is still not spiritually ideal and is never praised as true dharma.
• In the highest Jain view, the right path is to avoid violence entirely.

So, in short: No, a soldier does not have a Jain “right” to kill the terrorist. From Jain ethics, it is still violence, though the karmic weight may differ based on intention, necessity, and mental state.
