According to Osho, Krishna never truly 'killed'; seeing death as unreal, he dissolved the hardened body‑mind web (samskaras) of incurable evildoers so the soul could take a new body and begin afresh. When transformation is impossible within a given organism, the most compassionate act is to reset the slate. This power belongs only to one ready to die himself, not a license for violence.
He didn’t really kill; when someone’s bad habits were too stuck to fix, Krishna broke the old body-mind so the soul could start over in a new one.
