Karma: Definition of Karma

                                                                  Q. 1. What is Karma?
                                                                   
                                                                  A. Every action has its equal or greater reaction - this is a simple definition of karma. Whatever activity we do, good or bad, brings us good or bad reactions. Due to good karma, one may get a beautiful body, become wealthy or very intelligent etc., and bad reactions may come in the form of disease, poverty etc., or in terms of heavenly enjoyment or hellish sufferings and so on.

                                                                  Q: Given there is an all encompassing God/Krishna and given there is reincarnation and Karma, see Bhagavad-Gita 18.17, "One who is not motivated by false ego, whose intelligence is not entangled, though he kills men in this world, does not kill.  Nor is he bound by his actions."
                                                                   
                                                                   This seems contradictory to me.  The proof of a false ego is to dominate and control another unto death (killing).  It is not right to kill people and keep them from their  purpose in this life.  No one has the right to retard the education of another.  Saying he is not bound by his actions contradicts the concept of Karma.
                                                                   
                                                                   

                                                                  Q. 1. I am very unclear and confused. Bhagavan Shri Krishna says that all that is happening is predestined and nothing moves without His sanction. Then He says in BG 2.47 'Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion-at that time I descend Myself.'
