Answer

In Jain Dharma, a person can attain moksha only when all karma is completely destroyed. So if someone has mostly bad karma, moksha in the current birth is generally very difficult and very rare — but not impossible in principle.

Explanation

Jainism does not teach that a soul is forever trapped because of past bad karma. What matters is:

• Stopping new karma
• Shedding old karma
• Reaching complete purity of soul

A person with heavy bad karma can still begin the path now through:

• right faith
• right knowledge
• right conduct
• non-violence
• self-restraint
• repentance
• austerity
• meditation

However, moksha in one birth usually requires extremely advanced spiritual maturity and intense karmic purification. For most people, heavy bad karma means there is still much karmic bondage to dissolve before liberation can happen.

Spiritual Understanding

From the Jain view, no karma is permanent if one truly awakens spiritually. Even a soul with a difficult past can move toward liberation. But moksha is not achieved just by having good intentions — it requires the complete destruction of all karmas, both good and bad.

So the important message is:

• Bad karma is not the end
• Spiritual effort can transform the future
• Liberation is possible only through total karmic freedom

Takeaway

Yes, in principle moksha can be attained in the current birth, but with mostly bad karma it is usually not the immediate result. Still, the present birth is very valuable, because sincere practice can begin the journey toward liberation.
