In Jainism, actions that harm living beings or disturb inner peace are generally discouraged. Here is the plain, traditional view on the items you listed, framed simply and without mixing in other beliefs:

• Bad sex (lust/sexual misconduct): Sexual restraint is important for both monks and laypeople. Lustful actions that harm others, exploit someone, or violate consent are regarded as negative because they inflame passions and generate karmic bondage. For householders, moderation and fidelity are advised; for monks, complete celibacy is required.

• Alcohol and intoxicants (alcohol, ganja/weed/hashish, etc.): Intoxicants cloud judgment, inflame passions, and lead to harm to oneself and others. They are generally prohibited or strongly discouraged because they increase violence, deceit, and neglect of duties, all of which create negative karma.

• Gambling: Gambling is discouraged because it cultivates greed, attachment, and instability. It can lead to dishonesty, quarrels, and neglect of spiritual duties, which are considered harmful in Jain ethics.

• Masturbation: Jain texts emphasize self-control, especially regarding sexuality. For laypersons, moderate conduct and fidelity are encouraged; for monks, all sexual activity is forbidden. Masturbation would be seen as a violation of brahmacharya (celibacy) in the monastic ideal and as a source of wasteful passions for lay life.

• Animal welfare (and compensating after a few days): Ahimsa (non-violence) toward all living beings is a core Jain principle. Hurting animals creates karmic bondage. Caring for animals, minimizing harm, and engaging in compassionate actions (dana, seva, and other acts of kindness toward beings) are positive karmic counters. Jain practice emphasizes ongoing compassion rather than “compensating after a few days,” and atonement (pratikraman, confession) is not a substitute for refraining from harmful acts in the first place. The aim is steady self-control, right conduct, and consistent care for all beings.

Notes to keep it simple:

• Jainism places high importance on ahimsa, truth, non-stealing, celibacy or faithful conduct, and non-attachment. Actions that increase harm or craving tend to bind karma.
• There are differences in emphasis between Digambar and Shwetambar traditions on some rituals and vows, but the general stance above aligned with both: harm to living beings and loss of self-control are to be avoided; compassion and restraint are to be practiced.
• For spiritual progress, the recommended path is to cultivate right conduct (samyak avasāya), self-control, regular self-audit (pratikraman), and acts of mercy toward all beings.

If you want, I can explain how these ideas map to specific Jain vows or to common daily practices for lay followers.
