recently, i heard from Ven Tian Yin who was answering about Bodhisattva precepts, that non-intentional action also have non-intentional karma. He cited a case in the sutra, about this Bhikshu(?) who non-intentionally place a glass of water onto an ant(?) and crushed it. in the next life, the Bhikshu was meditating under a cliff, a boar came and was trying to scratch its teeth on a huge rock on the cliff. the rock fell and crushed the Bhikshu. the boar was the incarnation of the ant and had also no intention of killing.
Ah yes... thats right... when a person is not careful with his things, doesnt mean he wont commit karma!
First we must understand in terms of 5 skhandas. There is no doer of deed, and there is nobody experiencing the effect. It is made up of 5 skhandas, it is the Volition doing the deed.
When we speak of "intentions"/"volition", we must know that volition is part of every sentient being (5 Skhandas), so even though "he" does not know what he has done that, "his" volition of doing shall create the karma. Only an enlightened person can transcend that, that is Non-volition. But non-volition is not the same as not knowing because not careful. Non-volition must be understood in terms of Prajna/Wisdom. Without prajna, a person cannot attain non-volition. That is why an enlightened person no longer creates karma. Thus learnt from Thusness.
karma of killing is like this. if person A kill person B, person B will feel that he would want to kill back person A. to erase the killing karma, person B have to Forgive person A, hence the action of killing have to stop in either of the person.
when Buddha was a bodhisattva, out of compassion and wisdom, He killed the killer who was about to kill all the people on the boat. the bodhisattva actually took on the karma of reborning into hell for the killer. even if the action of killing is out of compassion, the bodhisattva(who have not reached a level of Tenth Bhumi) will still have to watch their Actions and intention.

Yes! A Bodhisattva does willingly commit "sins" for sentient beings. My dharma teacher herself also said, for example, if the dharma centre is full of mosquitoes/etc, she might take up the karma for the sake of spreading dharma for us, she might call the pest control.

But I think I don't have wisdom and I dare not take up karma for sake of others...
