In Jainism, sin (pāp) depends mainly on intention, carelessness, and harm caused.

• If you accidentally break an object with no violence, anger, or negligence, it is not the same as a serious sin.
• If breaking it causes harming living beings, anger, carelessness, or waste/destruction out of attachment, then pāpa increases.
• Jain ethics especially stress ahimsa and mindful conduct.

So, simply breaking something by accident is generally not a major sin, but if it involves violence or careless harm, it creates karmic bondage.

If you want, I can explain this according to Jain karmic theory in simple words.
