Hi Lal,
With regard to kamma patha;
The kamma patha that we generally refer to are the kamma patha for the dasa akusala. So for a kamma patha for panathipatha to be completed all those four conditions need to be met. If all those conditions are not met then the kamma of killing an animal will not be created.
For example if one tries to kill an animal but the animal does not die than the panathipatha kamma patha is not created. However with the thoughts, intentions and actions one makes towards killing that animal, kamma is created. So can this mean that different kamma patha are created for/at those different stages of planning etc.?
