Mahabharata — Anushasana Parva, Shloka 57
Ahiṃsā as Threefold Restraint (Mind–Speech–Action) and the Ethics of Consumption
यदि पुत्रसमं शिष्य॑ गुरुहन्यादकारणे । आत्मन: कामकारेण सोऊपि हिंस्र: प्रजायते
yadi putrasamaṁ śiṣyaṁ gurur hanyād akāraṇe | ātmanaḥ kāmakāreṇa so 'pi hiṁsraḥ prajāyate ||
玉提湿提罗说：若有师长因一己任性与欲望，无端杀害如同亲子般的弟子，则此师长亦成暴戾之人。权威并不能使残酷成圣：即便是导师，若循私欲而不循达摩（正法）行事，也必招致道德之罪。

Educational Q&A
Even a guru is not above dharma: killing a disciple without just cause, out of personal desire or whim, makes the teacher culpable and morally ‘violent’. Legitimate authority cannot excuse adharma.
Yudhiṣṭhira is articulating an ethical principle within the Anuśāsana Parva’s instruction on right conduct: he frames a conditional case about a guru harming a disciple to clarify that unjustified violence—especially by one entrusted with care—corrupts the doer.
