Our entire life is determined by our intentions. For example, take the following three cases:
1. You planned your actions in advance and murdered someone
2. A person accidentally died as a result of some event
3. You killed someone in battle during a war
Even though the action that took place is the same, we don’t judge it by the result, but by the intention. So, the intention makes all the difference.
