I agree with the criticism about the lack of polish in the articulation of the question, but I try to see if there is any there there, no matter how inarticulate the questioner may be(could be a second language issue). So...... I will try to keep my answer simple and easy to understand but hopefully of some depth in spite of all that. First, consciousness has a very large amount to do with Buddhism. There are the five skandhas ( https://en.wikipedia.org/wiki/Skandha )of which consciousness is one of the skandhas.
The subject of consciousness was considered so important that it became the point of a split off from Madhyamika Buddhism into Yogacara Buddhism with the assertion of the existence of alaya consciousness ( What is storehouse consciousness? ). Recently (january 17 to 22, 2013) there was a Mind and Life Conference where a prominent Cal Tech scientist (Christof Koch) had a dialog with the Dalai Lama where both Koch & the Dalai Lama agreed that panpsychism was a virtual sine qua non for forming a foundational understanding of consciousness and Buddhism.
So my answer is that the relation between panpsychism and Buddhism is of absolutely central importance.
The question of empathy is more difficult. I can't quote any Buddhist sutras on this subject but if there is empathy as an inherent aspect of consciousness, then it does not seem to manifest until the relevant organism has the ability to have a theory of mind ( https://en.wikipedia.org/wiki/Theory_of_mind ). It may be possible that there may be some form of subconscious or unconscious drive to include the consequences of one's own actions on other living beings (especially with respect to kinship factors https://en.wikipedia.org/wiki/Kin_selection ).
I suspect that(altruistic behavior) may be evidence for the possibility for empathy being part of basic panpsychic consciousness. For most people, however, there is an assumption of awareness of the emotional impact on the consciousness of the other that becomes an important consideration in karmic choices(volition, one of he five skandhas). I think the question is extremely interesting and wish more people had chosen to weigh in with informed responses.
