In Jain dharma, anger and the thought of harming someone are not good. They create pāpa-bhāva and bind bad karma, especially when they arise from krodh (anger), even if no physical harm happens.

But there is an important difference:

• If it was only a sudden thought or feeling after being woken up, and you did not actually act on it, the karma is much less severe than real violence.
• If you knowingly wanted to harm someone or actually tried to do it, that is a stronger sin.
• If it happened in a half-awake, uncontrolled state, Jainism recognizes that the mind was disturbed, so the fault is not the same as deliberate violence.

So, in simple words:

• The thought itself is not good
• The real sin becomes stronger when there is intention and action
• If you did not do anything, confess it in your heart, do pratikraman, and ask forgiveness

A Jain way to respond is:

• become aware of the anger,
• stop the thought,
• say mentally: “Micchāmi Dukkaḍaṃ”,
• calm yourself,
• and practice kṣamā (forgiveness) and samyak smriti (mindfulness).

So: yes, the angry violent thought is spiritually harmful, but if it was only an involuntary thought and no harm was done, it is a lighter fault, not the same as actual violence.
