Short answer: No, the Vaikriya Sharir (the gross body) itself does not knowingly do himsa. In Jainism, violence (himsa) is a karmic act performed by the jiva (soul) with intention. The Vaikriya Sharir is a non-sentient instrument made of matter; it becomes the vehicle through which actions, speech, or thoughts express, but it does not have independent will or intention to commit violence.

Key ideas:

• Violence arises from the jiva’s intent, not from the inert body.
• The gross body (vaikriya sharir) is simply the physical sheath; it can facilitate actions but does not itself “choose” to do harm.
• There are different Jain views on how karma aggregates through actions, but the basic point remains: intention behind actions is what binds karma, not the mere use of a body.

If you’d like, I can give a brief, canonical phrasing in Jain terms (arth) from standard digambara/shvetambara sources.
