In Jain Dharma, hिंसा is not judged only by what happens after death. It is judged by the intention, action, and the taking away of life.

Why a dead body is still not the same as natural food for sea creatures

If a body is simply left in nature and insects or sea creatures consume it, that is natural transformation of matter. In Jain understanding, this is not the same as a person killing an जीव.

But if a person kills an जीव and then says, “Its body will become food for other creatures, so it is okay,” that reasoning is not accepted in Jain Dharma.

Why it is hinsa

Because hinsa involves:

1. Intent to destroy life
2. Forcing death
3. Interfering with the soul’s natural journey
4. Violence done by body, speech, or mind

Jainism teaches that every जीव values its own life and wishes to live. So the principle is not “the dead body will help others, therefore killing is fine.”

About “Jeevo Jeevasya Jivanam”

This idea means:

• One living being supports the life of another in the world.
• But it does not justify violence.
• In Jain ethics, even if one जीव depends on another for survival, we must always follow minimum हिंसा, with restraint and compassion.

Important Jain view

A corpse being eaten by creatures is not the same as deliberate killing. Deliberate taking of life remains hinsa, even if someone later uses a “natural cycle” argument.

So in short:

• Natural decay of a dead body: not the same as hinsa
• Killing a जीव and justifying it by nature: still hinsa

If you want, I can also explain this from the Jain view of dravya, bhāva, and nimitta hinsa.
