Yes, merely “looking badly” (with lustful or impure intention) at women does give pāp‑karma in Jain Dharma.

1. Why it gives pāp even without physical act

In Jainism, karma comes mainly from bhāva (inner state), not just from big outer actions.

• Mano‑yoga (mind activity) includes:

- thinking, - imagining, - desiring, - enjoying mental pictures, etc.

If someone looks at a woman with kāmgraha / lustful dr̥ṣṭi:

• the mind is enjoying sexual thoughts,
• rāga (attachment) and moha (delusion) are stirred,
• this becomes aśubha mano‑yoga, which causes pāp‑karma and also strengthens sex‑related mohniya‑karma (veda, etc.). ( jainknowledge.com)

So even if:

• there is no touch,
• no words said,
• no physical act,

the mental enjoyment itself is a fault in brahmacharya and brings pāp.

2. Why it is “not mentioned” besides man–vachan–kāy

Actually, it is included there:

• Man (mind) – thoughts, imagination, intention
• Vachan (speech) – words, talking, flirting, provoking
• Kāy (body) – physical acts, gestures, etc.

“Bad looking” is:

• done through the body (eyes, face),
• but the real sin is from the mind behind the look.

So in Jain texts when they say: > pāp is done by man, vachan, kāy

they mean:

• any wrong activity of mind (mano‑yoga) – including dirty thoughts and lustful looking,
• any wrong speech (vachan‑yoga),
• any wrong body act (kāya‑yoga). ( jainknowledge.com)

They don’t list “eye” or “look” separately because it is already covered under:

• mind‑yoga (inner intention) and
• body‑yoga (use of the sense organs).

3. Practical Jain view

For both Digambar and Śvetāmbara traditions:

• Wrong vision (dushṭa dr̥ṣṭi / kām‑dr̥ṣṭi) breaks the spirit of brahmacharya,
• It is counted as hiṁsā to one’s own soul (hurting one’s purity) and cause of pāp,
• The heavier the passion and deliberate imagination, the heavier the bondage. ( jainknowledge.com)

4. What to do if this habit exists

In simple Jain practice:

1. Alochana–pratikraman: honestly accept, “I looked with wrong dr̥ṣṭi,” and repent.
2. Pratyākhyān (pachchhākhyan): take a small vow – “I will guard my eyes and thoughts better, at least for today / this week.”
3. Protect the mind:

- avoid situations, media, talks that trigger such looks, - practice samyak dr̥ṣṭi: seeing every jiva as a soul, not as an object.
